Description

We discuss the use of the Properties library for making SimPEG objects serializable and having validation on properties and classes.

A

It's going well yeah I, guess: I took over a bit of stuff up, Nate, nice and so nice.

B

A

A good deal, yes, I'm getting ready here, need to pack I. Think I start packing properly. This week still have.

B

A bit of time, oh.

A

The current yeah okay I have a few okay, a few from the church but other than that stuff. Hopefully you should be another run that idea. We know about.

C

Man know what gender is for sure, so I gotta help move.

A

On in June, first, okay, wait: no.

B

I, don't think so it's a like a relative! You just.

C

Never know that's, oh yeah,.

A

C

Feel that's a show.

D

Move some boxes.

D

They do have a lot of stuff gonna.

E

Organize slightly before we get move interest, just warlord yeah, exactly I, don't.

A

Worry anything other than that other than on my couch. That was so happy when I was moving. I actually made was helping you to move into my place, drunk as roll all those away and powerful and I was like yeah.

B

A

Place on the second floor,.

A

Stairs, except that other things should be fine, because it's ground all right: yeah Democratic, lure yeah, like a garden, your local, my place in yeah yeah. It's.

C

A

That's pretty awesome.

A

Our place is good spin it with us. How are you daddy.

A

F

My mom wasn't a sigh the float when she left this weekend so took her to the airport. That's what a stuffy yeah.

A

That that's a key how you should do backcountry yeah, oh yeah, this actually came along Scots crackers wait so they usually picked rock and a pulley up, yeah or yeah.

B

Other words, but I never sit here now.

C

Just arm grease with.

E

So all right, you guys want to start by um just like a quick overview of the presentation for people who weren't there any questions that are conversations that you guys had afterwards to ordered, particularly memorable or anything like that.

E

C

Over the main that I may not go at this people were shocked. There was free.

A

That was a marquee license. Mikey.

A

I think people appreciate it like, because the color code is more explicit and accessible yeah. It's like not.

E

A

A data that you they usually see in order inversion outfit but like whatever.

B

You wants could be accessible.

A

Yeah, why you know that yeah yeah I thought they they appreciate it and then now they thought like they could use, think that could be useful with their design. Their survey yeah well I'm, not 100%, sure they're going to use it because I get they may not even use any for Molly cook under design the survey it's like they use their experience Lee, but why there's some tricky part? They paint it. So I thought that's a good one. Yeah I got.

C

One thumb that they wanted to do it I'd love to see the code only blanket like a notebook. This is how to set up conversion. Okay, yeah.

G

Hey guys, can you hear me right.

E

Straight yeah I, don't.

G

Have my webcam but I can see you guys. That's.

H

B

E

We're just chatting about the BCTs presentation and like conversations afterwards, oh yeah now is there anything.

F

G

E

Out to you is people comments or questions you ought or anything like that.

G

Nothing in particular directly about some pig in terms of how to run it or anything. More just boardís questions about the case study I, presented.

C

Them with the answer that Peter about is no.

I

I, don't care right.

C

Cuz, that's to get a guy. That would be a tomboy yeah yeah.

E

I'll get back to him today. Cuz I want to sit up like just get him a couple examples of things we can start running with.

H

C

You know what he was talking about. Yes, so that sir, is done. It's.

G

Gonna say was that was that some kind of like test question of this is a really hard problem to solve, or no.

E

He's interested in like understanding the fields um do too and like an ellipsoidal uh inclusion or like an ellipsoid in a full space, just subject to a like uniform magnetic field right.

G

E

A time domain like a step off function, I.

A

Think the easiest place that you can start because you have all your the other book about the sphere in air and at once, I guess they cannot space vacant space, I.

E

Think that's why, yes, what I think what he really cares is.

A

About how time constant changes yeah and then on, like the issue of like how look so it like it like elongated, where so, but if you change that, like our time, constant changes, yeah America.

E

You have a pretty simple.

A

That's fear, yeah, so I think that's his name interest yeah, probably like using exactly the same setup and then just change the model yeah Devin like if you can send it to end Oh, to change the reach sure to flip story yeah and see all of that time. Changers I think that should be enough to start yeah. It uses a loop.

H

Source, but that's probably fine, that's.

E

A

Totally fine and then the he's it there. Some.

H

Time to make so yeah yeah yeah.

C

Were you dis could I ask you despot I, see, live, show yeah yeah, because he says that there's no I'm sure you look into it. So there's no, how to go. That's it for us, sir I think.

E

There there might be, but actually coding it up, I think is like just as involved, is solving it for me, eeehm problem. There was first fear the law, absolutely yeah.

H

J

B

Kind of its gonna do, is it's gonna, be fun to work with yeah I'm a little bit cat time.

E

Yeah, the other. The other thing that stood out to me at the presentation was also just like visualizing currents and fields that really seem to resonate with people, which is just cool, yeah, cuz I think that's something you typically I'm trying to pull out of another code. Yeah.

C

That's right there and it didn't seem to grasp to the fact that that was always there, but that remain accessible to the user. Yeah I.

G

Think that's really useful for just like the conceptual understanding of of what's going on for helping to understand your results to see you know where those fields are actually flowing. Are they is it going where you expect, or is there something else that you haven't expected yeah.

C

A

Yeah right yeah, there is nothing.

E

Very surprising.

A

We knew but like it's expected, but kind of showing that your expectation that not us yeah.

E

A

Peter other beer was mentioned, implying what he's working on. Oh.

E

Yeah so is working on like.

A

A strong memory system and what you definitely but, if they're, asking CGI to the inversion yeah, they still want to understand when they're developing your system yeah. So at that point like they don't care what the versions are yourself, what they want to sit away and see what's happening and that ability is all ability or something like that yeah. So.

H

In that case, like they're.

A

Something that they can fester drop like it, it out fast and see what they want view. Yeah I.

C

Thought that's really fit in what we're.

A

Working on because, like that's a research program, that's actually a research question, although they're in.

E

A

E

I thought: that's, oh.

A

Yeah we could even paint.

C

Them they're their own system and still feels right.

E

um Okay, so what I wanted to go over today was looking at perhaps a bit of how do we want to actually streamline setting up simulations and inversions sort of like driving, sim, potentially so I know we all sort of have our own approach right now to generating drivers and working with something. um It would be nice to try and like be a little more consistent and also streamline our own processes, them and I.

E

Think a lot of that will go into how we go about sort of refactoring district eyes so that it is like all the mesh classes are serializable, so use new, mascot, save and mesh download vegetable, okay, I think we're getting a bit of feedback or the conversation from you on your in.

G

Sorry say that again, I think.

E

We're going to just like a little bit of a background noise from you. Would you mind just maybe meeting your mic and then just unmute when you want to jump in set all right thanks.

E

Yeah so going through serializing things and then also streamlining how we need like set up and write scripts out, because I know, like often you want to set it up notebook or something like that, and then kick it over. The cluster and doing that in a notebook is, is like not the easiest. So I'll show you a bit of how I am working with this um and we can sort of freeform, as you guys have questions um so I'm just going to share my screen.

E

Okay, so first off, there's um two repositories: I'm going to be showing you, so these are both on github, it's under my name right now, so there's L Hagee base casing simulations, and this is just all the the Python code.

E

So I recently pulled these apart. So this is all Python code and then I've got one called casing notebooks, and this is just sort of a bit of a hodgepodge of notebooks and things like that, so the most recent ones are all in the casing: 3d, um okay. So let's take this example.

E

Make sure this.

H

Is like somewhat to date, that's not.

E

Okay, um I'm not going to run this because you a couple things that I've updated, but that's okay, um so the first thing I do is define just a directory of where stuff is going to be, and this is a round to anything that I'm going to create so that it knows where its own directory is. So if we actually look at the code, I'm actually just going to pull this.

E

So here um one of the first things I do is set up a like a casing. Parameters object, so this I recently updated just a little bit, so it's a little more modular. ah So what I have is a set of simulation parameters, and from this like this, to sort of the first thing, I set up that just is geometry and then maybe a couple parameters about the simulation itself, so frequencies and times because from there you then make all the decisions about how to design your mesh.

E

But the first thing is is just like: what's my model, so in this case, I've got a little survey parameters um class its frequency time, so you don't actually have to specify both these rights. It could be frequency or time or DC, and then I, but in these cases I'm only working with grounded sources, so I have both the source, a data source and then, like my my simplest class here, is I've got a whole space is going to be my model. It has a file name.

E

So this is what I'm going to save it to so that didn't know that about itself, so that when I do that full space not safe, it just looks here and says: where should I save myself?

E

It also it from base casing and inherits a directory. So when I set, this up I actually set a directory without so it knows it's directory, and it's so safe is enough, ah and then the whole space is simple. You know, we've got a SEMA back and a new relative back background um from there. We can define like a couple just handy things like skin depth and diffusion distance, and then here I also know it knows how to put itself onto a mesh.

E

So here it's quite simple right as all spaces, so the important thing to notice here is all of these guys are what's serialized.

E

So when I do a host-based I'll save these guys, along with the directory, and all of that is saved, go make sure you an example of that weather, okay, so I'm actually going to just start a new notebook, because that one's not gonna work.

H

You just double-check I'm in the right environments as well.

E

So here, let's just create a simulation directory just call it example.

E

Okay, so the first thing we can think about doing is I've got my pacing simulations and we're going to do a this is a now model and we're going to do a hold space.

E

So kids of things that I need to give it I'll give it a directory the file name. It actually has a default file. Name I'll show you that on you are back in a Sigma back a source, a and source B.

E

So here in this case, let's do my directory equal.

D

E

One mum, you are back one and then let's do resource a.

E

So, in this case, I'm thinking all in silk coordinates. So let's do it looks pretty clutter away and then do it. It.

A

Whole tip is like it's op, XY, that it's our.

B

Faith implies that.

E

Credit for this SIL mesh yeah, one of the things we can think about doing- is like making it easy to translate between the two. There are a few you tools for doing that, but it's not that the mesh itself works on so coordinates.

E

Okay, so that created a listening that guy. So this is my powerful trace fish. So then, if I do hold space dot serialize, these are the things that it's going to save about itself. um So it knows its class, it knows its directory, it's file, name background values, uh the source locations, and it also knows the version of the code, which is handy because if you save this and then I upgrade that like is non backwards compatible because know, what's happens so then I can always be like.

E

Oh yeah, I'll just revert to this version of my code and I can rerun this or you can like realize how you need to upgrade it so in this cage that I can do is in do whole space dot save all right. So it's saved that guy. So then, if I go to my files and my look at my casing- notebooks there's now this folder called example to the show yes, uh and so all it is, is just JSON Oh.

E

Okay: okay, um one other thing: I want to show you with that is in how you can load it back and I just need to recall my name's on this.

I

E

So I hold that guy model parameters, that's the default name all right, and so what this guy then does is I just wrote a little function that can actually go in and give in that file, because it knows its class I will just load it up and repopulate. So then, in this case a whole space, oh yeah, so with that it can do something like.

E

In this case, I need to tell it like where to look to recreate the thing, so this I just tell it case and simulations dot model. It's where to look for them to create the whole space.

H

E

Can show you the code for that if you want so in this case, I called that guy CP, which is a silly name, but that's when I started thinking about casing parameters. That's what is shortened through my head, so now that guy I've loaded it back up and I have my same class again. So if I ask it for this Sigma back I have my Sigma back. So then that's a very easy way to like build this guy up.

E

You can visualize it save it, and then you just have one command that says load this guy up. We are going to start rerunning simulations, so the code that actually loads that out is here, and so it's pretty simple and Franklin I'm sure you have some ideas on this and I would love to through them. So we opened up the JSON.

E

All I do is like ask you know: where should I've tried? What module does this thing belong to and then just recreate it so.

A

All of them, that's trinka, oh, so it's. How do you save match so.

E

They see a little funky right now and why I think it's funky is because we should actually just serialize the mesh um right now. I'm serializing, like a wrap all night I'll show you it I mean ah so in this case.

E

I'm just going to copy.

E

Some code and then I'll walk you through that.

E

Okay, so what with all the vacating stuff um there's some sort of odd meshes that I create, because we want to really finally district ties right around the well and then like pad out smoothly to sort of annex region where you actually on collect data and then pad from there. um So I don't want to coat that up every time, so I've sort of written a little wrapper that basically takes you know reasonable extent and goes from there and so I called those guys mesh generators.

E

And so here in this case, um if we look at my base mesh generator, it has a final name. It also it takes the casing, properties or casing parameters. Instance, okay, to build itself, because it's going to ask it's going to ask questions about the geometry of the casing. One thing I'm just going to do just so. This generates probably a better mesh, because I'm not sure how to work for the whole space is, let's actually just do a casing and a half space.

E

Let's make sure I've set everything: oh it's gonna taste, all of the parameters that need to be set have been set and we can actually have a look at it. So there's a couple additional things in this case: I have a casing diameter length. All that constant. This.

A

Is it like it when you didn't set it's like exactly that's a big fall yeah.

E

I have default in.

A

There and that's.

E

Something that like you as a developer, can specify like should. Are there reasonable defaults for these things, or should I force the user to actually set something mom.

D

E

Cool okay, so now that we have our casing model, um I'm, just gonna. Do this guys! Now my casing model, and so here this is now my mesh dot.

E

It's a casing, mesh generator, so I got a few different ones and there's in some cases I just want like a simple so much and then other cases you want this like funky casing one and not needs a few more parameters like those domain. Next to it whatever, so we just created a cheating match, um so I can do.

E

What guy- and so this is a 2d mesh um and then here, let's just generate a 3d to also compare.

E

It's when, if I do I met generator, crashed good.

E

So I've got a match that looks kind of like that. um So I'll show you what's on this mesh generator for the 3d one.

E

Okay, so there's a few more things, and this is something I'm thinking a little bit about too is I, don't actually know if we want to save this on here, not yeah, but we right now because the casing parameters are defined on there and serialized with it, and then it also has its sort of 2/4 cell sizes. So to find these two core regions, a cell size in the Z direction. I knows it's directory, so in this case I didn't set the directory, so the default is the current location.

E

I, probably don't want that so I can just do.

E

I set up, and now it's going to be example, folder and then it has its own default file name and then here I also had to serialize hy because I defined it specifically and then a few other padding factors and stuff like that.

I

May I ask you a question not on the serialization but on the cylinder mesh said: can you just go up to the picture gee? It's sincere! You don't discretize evenly in like a long. So theta angle is that's right. Yeah.

E

So, in this case, I defined my hy as a little stretched match. Essentially, oh so because, with the examples I'm doing I'm running a wire out along this direction, so that's actually the only workplace I really need to discretize. Okay, fine, so yeah, that's nice, but if I put in like the number 4, it will uniformly discretize it just like sort of when you're working with the typical tensor mention cool. Ok, so that gives us a mesh.

E

um So now the next thing we can do with that is now that we have a mesh and we have parameters. We can then piece together like physical properties on the mesh.

E

So what I've done with that is to find a very simple physical properties class, so I'm just going to scroll down and we'll go there, and so the distinction here- and this is something that I would appreciate opinions on is so the physical properties now only exist once you've defined a mesh and you define your casing parameters, so you have to define both to like have meaningful physical properties. I, don't know if it needs to be its own class, but it's kind of nice.

E

So what I do here is I, give it my mesh generator and my model parameters, and then it goes in and based on. You know the the model parameters have the method Sigma, given a mesh so now it'll define those guys as vectors and as properties you can also go in and like define, wires and maps and stuff like that. So this is I. Guess like a step closer to thinking about the inversion and then because you now also have the model and the mesh. You can go ahead and plot things.

E

So if I created this guy so soon this.

E

This probe is now.

E

E

It's not this physical properties object, I,.

K

D

Need to give it.

E

So we can go ahead and plot that and because it's a huge or not obviously seeing anything, um but we can do.

E

So we have UK tomorrow.

J

Yeah, so here, you're still, probably also that was a certification and like.

A

A receiver location, basically all started progress all the time. Staffs and frequencies is kind of true. So.

E

He knows that through the through.

H

The model is your mall Lukasik long yeah.

E

It's about something like I, don't know if we want to keep those apart into two things or not,.

E

But in some ways like I, like you, know, cuz, if I just do pacing model but Sinbad.

E

If I accept frequencies and things like that, like it, would you there's a default they're, just kind of nice.

C

True fits props and you kiss upon it says: yeah. Are they well.

E

Right now, it's CPE because of my silly, oh no I changed it whose problems dawdle. Yes,.

J

And how do you run this relation so.

E

In that case, what I then do is I've got this guy called run. So here what I do is I'll set up a casing, so I'll close, my simulation is now a casing: simulations dot, I'll shake code after first, so there's a base simulation in this case it has a field filing so because in like all the examples I want to run, I actually saf it yields so I get that just a name. It again has its own file name. So it's got simulation like if the simulation parameters should serialize.

E

um It now takes a casing parameters guide and a mesh generator. These ones I've created a property called of loadable instance. So in this case, I can give it a file name and I will just go and load it. um So I can show you that.

H

E

Right above that, so that guy is wrong base, so here all it does is um it is either an instance. It is either like an instance. Sorry that got screwed out these, um so it's either just in instance, or it actually is a file name that I can then go and load, and so why that's handy is when I just create like one of these simulation files, I condition, seed file names. Then it goes and recreates everything.

E

um So that is a piece of it. So if we go back here, that's what those guys are and the sanest source as well. So sorry we didn't creative source. So let's create a.

E

So I can create my top casing sorts. What does this take so that then takes the casing parameters.

E

It takes a directory.

K

Which is my isolation directory.

E

Finally, was fine and then my mesh generator.

E

E

That non y-axis line sources. Okay, so here what I need to do is stick this guy amp it up high a little silly, but just a safety check for myself.

B

E

Then I can also do.

E

So I know like where my little wire path is: okay, yeah, okay, so now I've got a source, we've got a model and we know- and we have a mesh ah so now we have everything we need to go in and create a casing simulation, so the assimilation is now using solutions got run, run, let's do DC, because that is faster.

E

So I would give you my simulation DC. So in addition that what the simulation DC actually has eyes, it has a source, a at source B. So this one's a little different because it doesn't actually take like the top pacing source. It doesn't need to compute the wire path and all that sort of stuff all it needs is just two end points.

E

If I take my time to make simulation, it's actually going to work with, like the the source that I've generated so I try to make any sort of interoperable Calphalon run a DC well and time domain or fluency.

H

E

What else um it also knows the formulation, the problem that we're working on, so if you want to go in and tinker with that, you can and then here I've overwritten the default to call it fields DC, because often it's been brought up with something else, so I don't want to overwrite it.

E

So here I will set that guy up so I've now got my kitchen. Routers is kitchen model. My mesh generator is Russian 3d. um My it also inherits the directory again.

E

And then my source a is just going to get my torch dug search today and.

K

E

Hey, so what just happened there and why it's taking took a second? Is it actually went in and set up a problem for me, so we can see some of the things that are on there is I've got a fields method.

E

It has now a problem, so it's got a problem. 3D PC pod has a survey and I've already paired.

E

So you can see that all kind of here it is- we've got the it's, it's self-doubt problem, sellout source survey and then it cared so I can actually go in and do similar to not validate before I actually go and on everything. What that's going to do is this going to check that my casing parameters are all set, my mesh is all set, my source is set, and that, like everything on my simulation, makes sense.

E

So that's nice, because this is something you can check on your end before kicking it over the cluster and like having to debug it.

E

Develop it looks like so: baladi is inherited from properties, and that goes in and checks like types of everything it'll check. So if I better required, it'll save a listing must be set, and then you can add your own checks as well like on.

K

The source I added some of those.

E

Checks, it's like hey, your mesh are, like I, haven't implemented this type of source. Yet so that's.

H

A

So if I, like I.

J

Can set the size of the source a something yeah.

E

Yeah so in this case, like it's a vector3, so it should, you know, have like an XYZ location and if it doesn't, then it's gonna error on me.

A

But like can I do a little bit more complicated things like say: I, don't have a source locations and it should be below to pause, for instance, yeah. How do I, how do I get that end to method structures.

E

So, in that case, you would um like inherit vector three and extend it. So that's what I did when looking at that, like instance, so that was in base. So here when I talk about a loadable instance, I I took properties on instance, so I get everything that I was.

A

Sorry and then I have an extra, so I can actually have custom yeah yep.

F

Just to illustrate energy.

H

F

Can also be found.

G

E

Scenarios on the.

G

House perhaps the classes class I just addressed and recommended.

F

As though, like properties, a validator, oh.

E

F

Then those those get called when you um call validate as well.

E

Do you have an example of them.

F

I'm not sure, probably well, let's see, let me look at that. Oh I.

E

Guess like actually it's like this right. Oh.

F

Yeah, okay, so yeah! So when you do that that that Vout, that validator runs when you set CP. But if you just if you just do at properties validator with nothing else,.

E

F

Then it only runs when you call validate: oh, it just takes self, the call signature just takes self, and then you can do whatever you want to validate. So you can say, like whatever yeah self dot CP equals something whatever oh I, don't know yeah. So.

E

I could probably do do you.

E

E

Oh yeah, so just extending this guy. Basically oh.

F

Yeah, so so what that method actually does is it calls all the registered class validators? So you don't really have to extend that guy. You just wrap something else in the at properties. Validate I, don't know, I can I'm. Looking at the docs now to see there isn't a great example, but I can you throw together something that.

E

Would be great.

F

F

So here I'll throw this in slack. This is the documentation page for it, but the examples are really not not very thorough. That's.

E

Right, there's.

F

A good one, a one-liner example.

F

Cool so yeah, if you see where I have mode one so mode one, that's how you're using it now yeah that sort of validator gets called on set. Okay,.

E

F

If you scroll down to mode two and that just shows how to how to do it, the other way, oh cool.

E

Nice, so that's actually something kind of cool if you had like properties of two different two different property has properties classes that you then want to check like something is kosher between them.

E

That's that's a very cool I. Do that yeah.

F

Yeah, and if you, if you, if you have like two two different properties that you have to set independently they're like have to be cross validated yeah,.

E

F

Like when you set one, it might fail because the other one hasn't been set yet, and so you can never actually set them. So you put that kind of logic in there too. Okay.

E

F

Just say: okay now I've set both of them did I set them correctly. That's.

J

E

So there's a couple other cool things: I want to show you about this.

E

So now, I have there's a few methods here that are pretty handy, so I have right pi, which is actually going to write a break on function of itself and then I also have run, which knows how to go ahead and run itself. So all that right, pi does. Is this C it's going to save each of these guys and because they all know their own names, they all know where they are. um We can write that out like in a very declarative way. So if I do.

E

Okay, that's right! So, let's look at. Instead, let's look at a time domain yam example as I didn't write it for just itself, and we can do this on the shooting rash if we actually want to run.

E

Into issues now, you call it source.

K

E

That's fair because I defy my source of my 3d mesh.

K

J

K

Too honest our.

J

Skin is actually on the bottom yeah. What was SRC there like this Kevin, wait I'm sure to find it, um but it seems like your times that was your time. Steps right.

E

I did not define time steps, that's fair, okay, so that is on thanks, Augie. So it's on my casing parameters. So, let's update the casing model.

K

E

So that shouldn't potentially work cool okay, so now we have a 3d time to am sanitation, um so if I do double check it cool. So now, if I write my Python file, so it's saved for different things. So it's saved example, my parameters, JSON model parameters, my source and my simulation dot pi. So what simulation dot pi looks like.

E

This so in this case, I wrote a couple things that, like are just handy for me, because the 2d simulation is dirt cheap and in the DC simulation is dirt cheap, so I just assumed that any time I'm going to run something in 3d I also want those, and you can set those as parameters like in the right function. If you want it, yes or no, ah so let's have a look at this. This is actually. This is all that's really needed for the the main simulation the rest is now actually constructing.

E

You know something that's comfortable in 2d and in DC, but like this is sufficient actually going around so I set up. My I recreate my simulation, so here this is where it's using.

E

That loadable instance is that I've just said, use the file names, and this is where you're going to save it to and then simulation dog run, it's going to run up and save my fields and then here because, like it's easy to generate the 2d mesh from the 3d one, that's all that these steps are doing is just saying like hey, you know, hy is actually just cylindrical asymmetric and then please create a 2d source from my 3d one and then run my 2d simulation.

E

That runs it and then, similarly for DC.

E

So this is then like this directory is all that I would kick over to the cluster and then just I always run it in ipython and I would just do button simulation dot. Hi! That's.

D

E

And then what's nice is is like to load everything up again. This is all you need right is I can, on the back end now, when I want to look at my results, this is all that I. Do is I, create this thing again and then I just load out my fields, because it's just I'm hiring right and that really populates.

H

Everything so it like you can work in visualize, so you're, basically at that through JSON file to run.

A

Simulation yeah.

C

In the JSON, because of our are all the variables all the parameters, there are only those that you want to know you want. You want to touch. She.

J

Say they hold primaries all the default parameters? Yeah.

E

Yeah I saved, like I, saved every every parameter that is basically necessary to declare um like how to create.

C

Your simulation, okay, that's not only fault and evil, don't have to be there, but all right that we're at a default interest. The.

H

Defaults are written out.

E

And saved oh yeah yeah, because if you ever going to change your default or something like that, yeah.

C

Yeah this instance, you can burn yeah.

E

Yeah, so it's pretty simple and like I I realize there is lots of code here, but this is actually all it takes during simulation, which.

H

E

C

Yeah so I'll be force, because we were playing about doing this for in versions right. We can write out the Python files, yeah yeah.

E

C

Have to create that a inversion like your sim yeah, so yeah.

E

I think so um so the way I would then think to piece that together is that you know how, like a way to build up your regularization, your data misfit list out the directives, and all of that so I, guess that, where I see this moving, a bit is realizing that, like the way I've defined sources and things like that, that that actually should be or the way it, especially if serialized, the mesh that should be baked in in peg, there's no reason that I actually need like a mesh generator other than like my custom pieces, but the simpad match should serialized right and be able to recreate itself, and so the biggest thing in being able to do.

E

That is actually just specifying. What are the pieces that you need to have saved in order to recreate it? So in that case, like bridges, a j hy which set a time for intensifies gansley and then the rest of the things can be figured out from tree mesh will be a few more things but yeah.

A

Yeah, that's great, that's great and it's potentially like even the same engine could be used for different different applications like there's like vm code, either multiple allocation, yeah, even the see a thing, so you can kind of make some customized simulations version. Yes, yeah yeah, ha that's nice! I really want to play with that. I kinda want to build something similar to seem sure sure, yeah.

E

K

A

Say yes, generating some file with simulation and aversion yeah and also put.

J

Some valve eight yeah.

J

E

Then it's taste like all these little plotting functions and things like that are just they're, so simple, but it's actually I mean it's a timecode, get right that plot, but I don't want right every time, but because part of my validation for this is like I visually look and make sure that you know the wire path is connected.

J

That's potentially what we need.

A

It for because, like every application, is something specific yeah and then you're not going to change all the main codes, like whatever you're doing that, probably having something else, I can handle yeah. Those things will be really great to them.

E

Yeah but I think as long as we can save all the things reload them easily and then make it easy to extend and that's what I actually like right now about where the model code is going on, because in this case, like I, have a whole bunch of different types of models, each of which is there's just like a slight modification to um so like a casing in a whole.

E

Space just inherits a whole space, and this parameters casing powder mix in and all that this guy knows how to do is like given a background model, sticks and casing in it. ah So.

A

I look again because all things are tangled: it's not a separate thing. It's some.

E

Information of the.

A

Survey, it's a gender to match yeah and also good information nationally. Oh oh yeah, but like a idea of passing yeah.

E

Cool yeah so, like I, think the first step is see realizing the mesh and serializing problems. It's like just writing out. Concepts is the the biggest thing for you know, kind of a problem, and it's tight in all. This are just done.

E

Yeah so feel free to poke around in here and like look at ideas, ask a bunch of questions. If there's stuff that you're unsure about the things that there's a lot of pieces that could be ported over, but it's I mean I. Don't wanna! Do that if it's confusing to people cuz I, think the purpose I.

C

Probably some time to digest yeah yeah, it's more about for the long-term idea of being able to be reproducible and investor Bruce get.

E

In here you want to say say.

C

A peer expert, well yeah, well.

E

In being able to do sleep batch generate a whole bunch of things, because now you know if I want to go in and like change the air conductivity and run ten different simulations. I can just like write a loop that says change my casing browsers and then write my files, yeah.

A

E

C

Better and I'm also thinking when you were, you know, let's say Craig or Jeff yeah yeah scripts, and then we don't change it, but the base code and they need to change all the screws, yeah hope and change of our walls that may just regenerate for them. Yeah yeah, because here to grow and change via the base coat yeah.

E

Just stop sharing and see: if do you guys have any other questions comments Craig in Franklin.

G

Now that looked good, so it's JSON Qualls you, like I, missed a bit. Let me get working somewhere.

E

So you cut out just very briefly your comment. What was your question there? Oh it's.

G

Just about the JSON files, I I wasn't quite follow where they they're they're written somewhere as part of the generating process. Alright, yeah.

E

So, in this case, like with any of the models or objects, I have that are these serializable objects. I on them is the directory and another property is its own file name and it just saves to JSON so JSON a lot like a Python dictionary. Basically, okay,.

G

Yep yep cool can.

A

You write it like an Oracle. Ii I got it's annoying.

A

H

E

Oh, it's a bit serializes Wallonia.

A

Nobody not writing out the Driessen file. Can your vitami cleveland they the parameters on the vertical direction cause like.

C

It's going to a rap, just go, get I'm, just y'all! Don't like rap on your pilot, oh yeah, fix of heck you might or either legit yeah, and you unwrap them. Your partner.

E

Franklin, would there be any like benefits or drawbacks to doing that? Does that matter? Sorry.

F

I didn't really follow. Oh just.

E

In like putting a line break after commas in the JSON, oh.

F

Yeah I mean I. Think that's just like a printing things which depends how you read it I'm, not sure, like that, I think that wouldn't I don't know I, don't know what like json dot load string does with line breaks.

F

Sorry I have to. I have to cut out quick yeah I have a few thoughts about property stuff that I'll follow up with you on okay.

E

Sounds good thanks for coming.

F

Yep talk to you soon so.

E

um Yes, I think you can I've played around with JSON and JSON, but loads and stuff, like it actually right now, I'm leveraging the properties serialization, so I just dumped it. The way that, because it.

H

Would be nice because come yeah yeah.

A

E

Is cross-eyed I still.

A

See those values, flash I mean I was really like, because sometimes they get change set of problems and spare.

C

To scroll balance, I know that's very character.

H

That's great ah and it's.

A

Obvious it's up as a value of the.

H

Variable and the.

A

Sun Valley.

H

A

C

Right user user, friendly yeah.

E

Cool any other questions comments, things mystery, oh.

H

Yeah thanks thanks for the seat here, guys thank.
