Description
Weekly SimPEG meeting from May 5th, 2021
A
C
Yes,
right,
yeah,
it's
next
tuesday
at
1pm,
pacific
time,
so
we're
talking
about
pgi,
of
course,
but
I
will
try
to
put
that
in
the
broader
context
of
what's
been
happening
in
joint
inversion,
either
from
csm
and
other
places
like
my
max
maximum
camp
work
etc.
So
getting
like
a
view
of
that,
so
I
will
actually
try
put
the
link
here,
like
maybe
in
the
chat,
and
I
will
add
it
to
the
note
as.
A
Okay.
Well,
then,
if
there
isn't
any
other
announcement,
we
can
get
on
some
quick
reports.
I've
opened
a
new
pr
and
sim
peg
to
update
the
boundary
condition
like
the
dc
code
to
use
any
boundary
condition
stuff.
Simplifying
it
right
now,
there'll
be
a
few
there's
a
few
linking
errors
that
we
need
to
like.
At
this
point.
It
probably
has
to
be
a
slight
ignore
because
it
has
to
deal
with
renaming
things
from
master
to
main,
so
I've
gone
through
and
updated
most
of
the
links
to
point
to
main
branch
instead
of
master.
A
A
A
A
A
B
He
wasn't
using
it
at
all,
and
I
was
looking
for
examples
of
how
to
use
it
and
access
it,
but
most
of
the
stuff
I've
done
like
it
gets
buried
in
a
complicated
plotting
function,
and
so
it's
actually
really
hard
to
tease,
tease
out
what
we're
doing
so
wanted
to
just
put
it
on
the
table
and
ask
if
folks
would
be
interested
in
tutorials
around
sort
of
using
the
fields
object.
So
perhaps
adding
that
one
to
each
method.
B
I
don't
think
it
would
need
to
be
super
in-depth,
but
a
simple
example
or
tutorial
on
like
what's
available
to
be
accessed
from
each
of
the
fields
objects
in
for
each
of
the
different
simulations.
So
it's
probably
a
question
mostly
for
for
devin.
If
you
yeah
would
be
game
to
take
something
like
that
on
it.
At
some
point,
I
don't
think
it's
super
urgent,
but
I
saw
that
kind
of
surface
is
a
bit
of
a
need.
D
Yeah,
no,
I
think
that's
a
really
good
idea,
because
we're
not
always
just
simulating
data.
Sometimes
you
want
to
see
what's
actually
happening
within
the
entire
domain.
So
I
think
I
kind
of
looked
into
that
at
one
time
but
a
while
ago,
but
maybe
there
were
some
changes
with
how
we
were
managing
fields,
and
I
decided
to
just
kind
of
wait
until
it's
in
its
final
form,
but
it
would
be
really
good
to
add.
A
B
Yeah
I
mean,
I
think,
there's
potentially,
I
guess
I
have
two
thoughts
on
this.
There's
part
where
I
think
that
we
should
actually
refactor
a
bit
of
the
fields
object
and
rather
than
having
it
be
this
like
smart
dictionary.
It
just
be
methods
like
electric
field
fields,
dot,
electric
fields
and
then
you
just
pass
it
the
source
and
anything
else.
E
F
E
F
G
You
guys
have
a
quick
update,
there's
a
hairdryer
going
in
the
background
here.
So
I'm
sorry
yeah
just
getting
back
into
the
swing
of
things.
I
just
got
off
the
project
and
yeah
coming
back
to
reality
into
civilization
and
getting
back
into
it,
but
I've
started
finishing
up
that
document
for
starting
a
kubernetes
cluster
so
that
yeah
run
on
that
tiling
and
you're
gonna
set
up
a
nice
fast
network
should
have
that
done
by
the
end
of
the
week
and
yeah.
It's
in
a
curved
note.
G
H
B
A
A
D
D
So
there's
there's
some
movement,
not
at
the
rate
that
I'd
I'd
like
but
yeah.
It's
pretty.
I
think
it's
pretty
important,
so
I'm
trying
to
put
in
some
work
on
that-
and
I
guess
soggy's
not
here
today.
So
I
might
add
another
thing
joe
soggy
and
I
met
on
friday
and
came
up
with
a
an
action
plan
for
em1d.
D
J
J
Yes,
I
think
I
did
the
first
path
for
both
of
the
codes
and
yeah.
It's
actually
like
it's
working
well,
the
serial
version
is
actually
faster
than
the
previous
one.
I
think
it's
mostly
joe's
that
function
that
computes
the
reflection
coefficients,
I
guess,
but
the
parallel
version
is
actually
a
bit
slow.
J
I
which
I'm
not
so
I
was
actually
playing
a
little
bit
with
that
because
I
think
it
seems
related
to
the
overhead
about
what
we're
passing
it's
an
odd
problem,
because
the
each
one
this
simulation
is
really
cheap,
sometimes
it's
less
than
a
millisecond
or
a
lot
of
milliseconds.
So
if
the
overhead
is
actually
over,
then
more
than
millisecond
actually
you're
overkilling
with
the
parallelization
anyway.
So
that's
that's
where
I
am,
but
I
think
overall
things
are
things
are
working.
J
J
F
Hi
so
last
week
I
did
some
mino
updates.
So
remember
this
amino
updates
for
the
tutorial
of
cross
gradient.
So
remember,
last
time
I
showed
the
two
blocks
and
performed
the
giant
inverter.
We
can
see
some
linear
trend.
As
dr
sun
and
sagi
suggested,
I
created
the
three
blocks
with
different
susceptibility
and
the
density
values,
and
then
I
performed
the
giant
inverter
and
got
some
results
got
some
good
results
for
the
tutorials.
A
Dom
I
remember
you,
were
you
brought
up
to
me
when
you
were
you're
running
through
some
of
them?
Did
you
figure
out
what
those
issues
were
that
you
had?
I
mean
the
check
body
issue.
Tom
was
thomas.
I
think
you
said
you
were
running
through
some
of
the
tutorials
on
the
crossbreeding
and
you're
asked
what
the
issue
were
you
having,
but
did
you
ever
were
able
to
figure
it
out.
I
Yeah,
it's
the
self.kai
right.
So
basically,
if
the,
if
the
model
wasn't
set
on
the
simulation,
you
don't
do
simulation
model
equals
something
then
cell.com
is
not
defined
and
then
as
soon
as
it
hits
the
thing,
then
properties
is
unhappy
because
cell.com
is
none
yeah.
I
didn't
have
time
to
create
a
like
a
pull
request.
On
that
I
mean,
I
think
we
just
need
to.
As
you
said,
just
do
a
try
catch
right,
a
try
exception
on
the
on
a
self.kai,
I'm
still
very
unsatisfied
with
the
whole
properties.
I
C
Create
a
pr
that
brings
a
bell.
I
I
remember
that
like
when
I
was
like
when,
when
I
created
indeed
like
updated
pgi
to
the
simulation
class
et
cetera,
I
run
into
that
issue,
and
I
I'm
pretty
sure
I
put
a
pr
to
fix
that.
So
I
had
the
I
had
pgi
and
the
joint
tutorial
of
pgi
working
with
simulation.
So
so
it's
still
on
a
pr.
Are
you
thinking?
I
C
Thing
this
is
yeah.
This
is
well.
Let
me
check
back
again,
which
was
up
here,
but
that's
exactly
what
I
was
fixing
that
there
was
no
model,
so
instead
I
think
I
was
looking
at
something
that
was
like
set
like
the
shape
of
the
mapping
or
something
like
that.
So,
okay,
so
I'll
I'll,
let
you
look
at
it
before
then
you
pay
me.
You
pick
me.
A
After
you
look
at
them,
I
think
I
think
the
best
step
was
just
to
do
a
try
catch
like
try
to
accept
bracket
there
to
catch
it
properly
and
just
move
on
yeah.
It
means
that
it's
like
trying
to
access
something
that
doesn't
exist
yet
and
then
set
it
to
be
something,
but
it
wasn't
like
it's
just.
I
think
whatever
tivo
we
have
done
to
update
that
functionality
just
tweaked
it
a
little
bit
way
that
wasn't
quite
correct.
So
I
think
the
best
best
process
is
just
you
know
like.
C
I
Yeah,
so
nothing
pushed
on
the
on
the
main
sandbag,
but
the
past
two
weeks.
I've
done
a
lot
of
work
on
the
on
the
zed
them
our
like
natural
source,
tiled,
just
to
figure
out
a
strategy
for
you
all
to
tile
spatially
as
well,
and
then
find
out
that
we
still
needed
the
john
to
do
the
tipper
to
update
the
the
tipper
receivers.
G
I
G
I
And
then,
let's,
let's
talk
again,
I
guess
yeah
and
I'm
very
happy
that
you
guys
are
working
on
the
m1d,
because
we
want
to
update
our
applications
to
be
able
to
run
on
14
0
14,
but
yeah.
The
em
1d
stuff
is
kind
of
critical
for
for
us
to
be
able
to
pull
the
plug.
So
I'm
quite
excited
that
you
guys
are
working
on
it.
Thank
you
very
much.
G
G
E
I
E
I
E
Well,
yeah:
we
will
need
the
data,
but
that's
lower
prior
priority
list,
just
to
try
to
get
re-familiarized
with
what
what
we
were
trying
to
do,
and
I
remember
we
had
some
work
workarounds
for
you
know
getting
like
approximate
effective
magnetic
susceptibility
using
the
borehole
stuff,
but
we
never
really
tackled
that
head-on,
and
this
is
a
good
time
to
do
it.
So
la
paloma,
I
I
think,
was
certainly
one
place.
E
I
Think
it's
better
because,
right,
as
I
told
you,
barrack
doesn't
hold
the
property
anymore.
So
you
know
the
rights
of
being
publishing
the
the
the
results
were
going
to
be
a
lot
harder
and
kevin
said
we
have
a
full
3d
georgico
model
for
it
with
tons
of
boreholes.
So
you
know
to
me
it's
more
interesting
but
yeah.
I
F
Will
do
it
hi
dog,
hi,
dog
yeah?
I
just
realized
the
the
question
you
just
asked
me
about
the
homomagnetic
data,
so
yeah.
As
I
know
at
this
moment,
nobody
in
our
group
do
the
work
related
to
both
magnetic
or
gravity,
but
I'm
not
sure
whether
dr
sun
has
these
data,
because
I
think
the
idea
and
the
data
they
have
is
way
much
more
than
the
students
here.
So
maybe
I
can
send
the
email
and
assistant
to
you
and
lindsay
to
ask
him
whether
he
has
some
author
magnetic
data.
