Description
SimPEG meeting on November 27
A
A
C
C
Basic
website
retracted
target
and
so
yeah
your
changes
were
some
suggestions
on
changing
a
couple
sentences
and
changing
some
variable
names
and
something
about
formatting
the
strings
for
some
of
the
and
so
I
did
that
and
the
test
fails
that
build
properly,
but
I
think
one
of
the
things
I
did
was
I
deleted
the
the
auto-generated
stuff
from
Spinks
gallery
for
the
examples
and
I'm
wondering
if,
because
I
did,
that
it
sees
it
as
change
or
something
Travis
has
to
recheck,
and
not
one
of
those
examples
is
failing.
So
I'm
not
you
know.
C
A
Thanks
Devon,
this
one
was
a
weird
I'm.
Sorry,
I
haven't
had
a
chance
to
actually
pin
you
on
this
I,
just
sort
of
started
playing
around
with
it.
This
morning
it
looks
like
it
was
just
an
issue
with
the
version
of
things
so
I
like
actually,
as
you
were
speaking
I,
created
a
pull
request,
8:29,
which
at
least
the
push
passes
so
I,
but
the
the
PR
should
pass
and
that
should
hopefully
fix
fix.
A
C
E
A
It's
in
the
depth
requirements,
but
I've
got
that
so
I
just
dropped
a
link
for
the
pull
request,
8:29
in
the
notes,
and
so
as
long
as
that
passes,
then
there's
nothing
that
you
should
need
to
do
so
we'll
get
that
in
and
then
I'll
merge
that
into
your
pull
request
and
then
as
long
as
that'll
pass.
This
then
then
we'll
get
it
in
yeah
yeah.
C
A
Just
to
chat
about
strategies
for
that,
especially
given
we
have
a
lot
more
users
than
that
are
not
vocal.
Then
then
I
realized
and
not
sort
of
came
to
light
when
I
was
in
Colorado,
which
is
super
cool,
but
it
also
means
we
need
to
be
very
intentional
and
thoughtful
about
how
we
do
this
refactor
yeah.
A
F
F
G
D
Nothing
in
particular:
what's
there,
I
we
had
a
meeting
in
Stanford
for
our
groups
like
it's
like
a
consortium
meeting
but
kind
of
the
audience
is
a
little
bit
different,
it's
more
like
a
local
agencies
and
water
agencies,
but
there
there
was
a
little
bit
more
and
positive
conversation
about
kind
of
like
a
in
a
in
a
state
level
using
some
open
source
to
show.
Let's
say
how
elbonian
works,
I'm
like
it's
just
a
like
it's
just
a
seed
at
the
moment,
but
I
think
yeah.
We
can
actually
sneak
in
and
use
impact
to
show.
D
D
F
D
D
You,
if
you
look
at
one
of
our
paper,
the
canucks
paper,
ladies
ducks
paper,
we
did
that
during
conversion,
exactly
what
you
said.
So
we
already
resolved
nano
time
and
one
of
the
airborne
platforms,
so
we
actually
invert
a
three
different
inductive
source
data
to
just
for
a1
model.
So
you
could
do
that.
Okay,.
A
F
D
B
Let's
see
so
I've
been
traveling,
but
we're
back
now
for
a
few
days
achieved
the
trip
to
mind
Mar
was
actually
really
successful,
so
we've
talked
both
at
the
people
at
the
national
level,
as
well
as
at
the
state
level
and
cut
a
long
story
short.
Basically,
the
project
that
we
were
planning
from
the
Geo
science
Without
Borders
has
not
been
related
to
a
national
project
and
the
give
us
a
lot
more
visibility.
It
also
greatly
enhances
our
chance
to
make
an
impact
and
I
think.
B
Maybe
the
one
thing
I
is
worthwhile
saying
here
to
this
group,
is
that
I
think
right.
Now
is
the
perfect
time
for
us
to
concentrate
somehow
and
consolidating
like
all
of
the
various
pieces
of
information
and
whatever
format
they
have
for
the
DC
resistivity
problem.
So
we've
got,
you
know
the
GPG
we've
got
EMG
si
we've
got
simple
examples:
soggies
been
developing
some
2d
inversions
Lindsey's
got
some
1d
inversions
and
forward
modelling.
B
This
is
an
opportunity
to
kind
of
think
how
we
might
want
to
restructure
some
of
that
material
so
that
it
can,
you
know,
really
make
an
impact
kind
of
long
term
and
for
various
places.
Certainly
if
we
are
successful
in
Myanmar,
then
the
material
that
we
develop
will
be
extremely
useful
for
any
place
else.
You.
A
B
B
Yep
I
think
that
would
be.
That
would
be
great
yeah
I
need
the
thing
that
we're
up
against
in
Myanmar
is
that
you
know
people
there
have
a
very
low
kind
of
background,
both
in
science,
certainly
in
computing
aspect
and
also
in
yeah
kind
of
yeah,
critically
thinking
and
how
to
kind
of
go
about
really
getting
information
from
the
data.
So
all
of
the
resources
that
we
can
put
together
from
the
point
of
understanding
and
importantly
also
from
the
point
of
view
of
you,
know,
collecting
data
and
what
to
do
with
it.
B
C
Thoughts
on
this,
the
first
is:
are
you
proposing
you're
not
proposing
any
kind
of
changes
to
the
content
of
the
TPT,
because,
as
it
stands
right
now,
the
purpose
of
that
was
to
be
a
textbook
for
her,
an
undergraduate
level
introductory
geophysics
course,
and
the
way
that
that
package
has
been
sort
of
completed
works
very
very
nicely
at
this
point.
If
we
start
to
I,
guess,
add
things
or
take
things
away.
C
That
could
lead
to
a
lot
of
work
for
managing
materials
related
to
a
course
that
works
quite
well
now,
as
far
as
maybe
adding
content
to
EMG.
Oh
sigh
I
think
there's
some
spaces
and
some
things
that
are
maybe
not
filled
it.
If
I
was
going
to
add
this
kind
of
content.
For
me,
that
would
be
maybe
for
the
GPG,
so
I'm,
sorry
for
for
EMGs
I,
that's
sort
of
a
platform
for
that
I
thought
that
was
kind
of
the
purpose
of
that
website.
To
be
honest.
Well,.
B
It
was
I'm
not
sure
that
it's
actually
structured
as
efficiently
as
it
could
be
from
the
point
of
view
of
somebody
just
being
able
to
you,
know,
step
in
and
and
do
something
and
at
the
same
time
there's
a
number
of
examples
that
we
need
to
perhaps
do
within
simple
and
some
documentation.
There's
just
a
lot
of
things,
I
think
to
be
done.
Yeah
I'm,
not
suggesting
that
we
go
in
and
alter
the
GPG.
C
C
Right
now
is
a
Google
Doc
that
says:
okay,
I'm,
starting
out
with
some
data
and
topography
and
ultimately,
I
would
like
to
invert
or
get
a
best
interpretation,
and
we
went
through
the
the
thought
process
and
the
the
best
practices
for
somebody
who
wanted
to
take
MT
data
and
get
a
recovery
conductivity
model,
and
there
might
be
with
what
we
do
now.
There
might
be
space
to
have
something
like
that
on
this
impact
website,
which
would
have
kind
of
an
extended
or
applied
eh-2-zed.
A
Do
you
have
I
know
that
you
and
Ren
were
working
on
a
bit
of
like
a
course
outline.
We
also
have
everything
from
the
disc
like
the
slides
and
and
that's
sort
of
ordering,
because
I
think
that
EMG
OSI,
ideally
we
restructure
some
of
that
to
start
looking
more
like
the
disc
mm-hmm
again.
This
is
actually
something
that
we
need
to
make
sure
that
we
actually
create
like
public
announcements
about
there's
a
lot
of
people
using
EMG
si
at
Colorado
School
of
Mines
very
regularly,
and
so,
which
is
super
cool.
A
But
that
also
means
that
when
we
like
change
the
links
and
break
them
all,
we
want
to
make
sure
that
we've
informed
people
sort
of
why
we're
doing
this
and
that's
and
that's
fine
and
that's
something
that
we
can
be
thoughtful
about
when
we
merge
pull
requests
and
and
bump
version
numbers
and
things
like
that
yeah.
But
if
you,
if
you've
got
a
Google
Doc
going,
then
maybe
what
we
can
try
and
do
is
like
parse.
Some
of
that
and
say
like
this
chunk
fits
jpg.
This
fits
mg
si.
A
B
I
think
not
it's
just
something
that
I
kind
of
wanted
to
bring
up
now,
both
because
of
we're
just
been,
and
also
you
were
planning
to
go
visit
or
do
this
project
at
the
beginning
of
February,
which,
because
of
the
December
holidays,
is
going
to
come
up
extremely
quickly.
But
the
other
thing
that
I
think
is
also
important
here
is
that
we're
going
to
try
to
identify
these
trainers
that
we're
going
to
develop
and
they
have
acquired
data.
B
This
is
the
National
DRD
in
various
states,
and
they
have
inverted
it
in
1d
and
made
some
interpretation.
So
what
I'd
like
to
do
is
to
start
getting
people
in
Myanmar
kind
of
connected
with
these
data
and
the
use
of
our
one
decodes
to
in
reinterpret
the
data
and
see
what
how
it
matches
what
they
had
before
and
to
start
generating
some
case
histories.
So
in
order
to
do
that
right,
we
need
to
have
kind
of
the
resources
in
a
format
that
they
can.
B
You
know
easily
go
ahead
and
use
at
this
point,
and
since
some
of
these
people
will
have
no
real
background
in
great
many
things,
this
will
be
a
challenge
to
deciding
what
to
present
what
to
show
them
at
any
particular
time
in
their
quest
and
have
it
have
something
useful
that
they
could
get
it
done.
Okay,.
A
Well,
give
a
couple
updates
on
Clara's
phone
lines
and
then
just
some
other
random
things,
and
then
we
can
circle
back
with
whatever
extra
time
we
have
been
maybe
dive,
but
a
little
bit
into
the
utils
discussion
spend
a
bit
maybe
on
a
the
groundwater
project
and
heat
resistant,
and
if
anyone
else
has
items
feel
free
to
like
add
that
as
I
ramble
along
so
there's
I
just
dropped
two
links
in
the
notes.
So
the
first
one
is
a
couple.
A
Basically
the
unpacked
some
of
what
we
have
in
the
apse,
because
she
wants
to
be
able
to
go
in
and
edit
the
figures
and
things
like
that
and
that's
harder
to
do
from
the
apps
than
it
is.
If
you
just
have
access
to
the
the
raw
code.
So
if
anyone's
willing
to
just
like
take
a
look
and
feel
free
to
add
comments
or
if
there's
things
that
you
think
could
be
helpful
to
add
there,
that
would
be
great.
A
And
then,
if
this
is
a
useful
set
of
examples,
then
maybe
it's
something
that
we
can
pull
into
this
and
peg
Docs
at
some
point
in
time.
Yeah
so
feel
free
to
feel
free
to
take
a
look,
and
actually
some
of
that
might
serve
the
GWB
project
so
worth
checking
out
yeah
and
then
last
week
I
was
at
well.
I
was
in
Boulder
and
golden
I'm.
Sorry
in
Colorado
all
week
went
to
Boulder
and
I
chatted
with
a
couple
people
there.
So
I
chatted
with
Leah
Wasser.
A
She
is
at
CU
Boulder
and
she
is
the
director
of
the
earth
he's
called
the
earth
lab
and
they
develop
a
bunch
of
educational
resources
for
more,
like
geospatial
analytics
they've,
actually
developed
a
bunch
of
notebooks
that
ended
up
in
software,
carpentry
and
so
yeah.
So
that's
actually
worth
just
like
taking
a
look
at
maybe
for
inspiration.
They've
done
some
really
nice
work
and
then
she's
also
the
one
leading
the
charge
on
PI
open
side.
A
We
know
the
editor
okay,
well,
one
of
the
others,
former
editor
and
so
Josh
you
can
publish
software
and,
like
the
review,
is
basically
just
like
a
checklist
so
you're
reviewing
for
like
are
there
tests?
Are
there
examples
or
the
installation
instructions
clear?
All
that
sort
of
stuff
pi,
open
SCI
is
a
bit
more.
A
A
A
Yeah
then
I
went
to
golden
I,
gave
a
presentation,
so
I
just
dropped
the
Google
slides
link
in
there
too.
If
folks
want
to
see
that
which
was
a
fun
presentation
to
give
and
then
I
ended
up
chatting
with
quite
a
few
students
there.
So
they
had
me
lined
up
for
a
lot
of
meetings,
which
was
which
was
fun
and
I
was
quite
impressed.
How
many
people
actually
basically
the
meeting,
was
they
pulled
up
a
notebook
and
like
pointed
to
a
line
of
code
that
was
simpang
and
said.
A
Can
you
explain
to
me
what
is
going
on
here
and
so
I
was
a
bit
taken
aback
by
how
many
people
were
we're
up
and
running
with
Simba
and
had
like
very
specific,
targeted
questions
to
try
and
understand.
What's
what's
going
on,
and
so
that
made
me
think
that,
like
prioritizing,
getting
a
discourse
page
up
and
running
I
think
is
important.
Slack
is
great
for
sort
of
real-time
communication,
but
in
terms
of
like
capturing
questions
and
capturing
content,
is
pretty
terrible
with
that
and
so
yeah.
A
So
I
will
try
and
put
some
effort
into
getting
some
initial
scaffolding
around
this
course
and
then
send
send
the
link
out
for
feedback
and
ideas
and
then
once
we
have
that
in
a
state
that
we're
happy
with
I
think
we
blast
out
an
email,
particularly
to
folks
at
Colorado,
School
of
Mines
and
just
say
like
hey.
This
is
meant
to
be
a
resource.
You
can
come
ask
questions.
A
A
We
haven't
really
used
mappings
with
anisotropy,
and
so
the
expectation
like
when
you're
sending
an
isotropic
model
into
the
for
word
problem
is,
if
we're
doing
a
3d
for
word
problem.
If
the
anisotropy
is
diagonal,
then
you
send
in
a
an
array
that
is
whit's
three
by
length
number
of
cells.
That's
diagonal,
so
Sigma
X,
Sigma,
Y,
Sigma
Z.
If
you
have
the
full
tensor
its
weight
six,
so
you
have
the
off
diagonals,
and
so
that's
fine.
A
But
that
means
then,
like
most
of
our
mappings
are
expecting
vectors,
always
and
so
we're
gonna
just
have
to
put
some
thought
into
where
it
makes
sense
to
allow
wider
arrays
basically
to
be
passed
around,
because
there's
some
places
I
think
in
the
exFAT,
for
example,
we
actually
flatten
whatever
comes
in,
and
we
might
not
want
to
do
that
yeah.
So
that's
that'll
just
take
some
thinking
and
sort
of
being
in
touch.
But
if
you
see
her
peeing
and
asking
questions
that
sort
of
the
the
context
just
to
keep
in
mind.
D
So
Lindsay
like
a
what?
What
kind
of
application
were
you
were?
They
kind
of
interesting
in
Colorado
School
of
Mines
like
MT,
is
a
good
example,
but
then
so
there,
a
lot
of
people
were
bringing
notebooks
and
asking
about
synthetic.
What
word
the
sort
of
main
application
that
they
were
sort
of
interested
yeah.
A
So
for
Yahoo
s
group,
it's
mostly
mining
and
oil
and
gas
applications,
there
was
actually
a
master
student
who
I
chatted
with,
and
actually
this
is
totally
relevant
to
the
GWB
project.
Who's
also
doing
when
the
DC
resistivity
soundings
for
groundwater
with
geoscientists
Without
Borders,
but
just
in
in
Africa
rather
than
in
Miami,
and
so
they
actually
also
need
coats
and
so
I
think
that
whatever
we're
developing
for
our
project,
we
should
absolutely
keep
keep
her
in
the
loop.
A
A
A
So
that's
a
satellite,
that's
been
launched,
I
think
it's
been
running
for
about
a
year
now,
and
it's
basically
lidar
from
space
with
green
lasers,
which
was
cool
because
green
is
tuned
to
reflect
well
reflects.
Well
off
of
ice,
so
it
measures
lidar
around
the
world,
but
it's
specifically
tuned
to
do
well
with
ice,
and
so
yes,
we
chatted
a
bit
about
that
yeah.
So
there's
quite
a
range
of
quite
a
range
of
applications.
There.
A
So,
for
the
most
part,
people
have
been
actually
just
like
very
excited
that
this
material
is
online.
When
I
like
to
point
out
that
I
think
the
organization
is
challenging
to
sort
through
they.
They
like
acknowledge
that,
but
they
didn't
actually
seem
to
be
a
huge
blocker
which
is
cool
and
so
for
a
lot
of
the
use
that
I
saw.
It
was
in
a
sense,
like
the
I
mean
the
fact
that
we
have
derivation
z'
and
things
like
that
in
there
and
discussion
around
that.
A
B
A
Yeah,
so
people
use
it
yeah
and
I
was
amazed
at
how
many
people
were
using
sim
cake
who
were
not
necessarily
in
touch
with
us
and
the
fact
that
they
were
able
to
get
up
and
running,
and
a
lot
of
people
did
complain
about
the
fact
that
we
don't
have
enough
sort
of
user
documentation
and
things
like
that,
but
they
were
very
excited
to
hear
that
Devon
is
championing
that
and
that
it
is
coming
in
the
pipeline
and
I.
Think
discourse
will
will
help
with
some
of
that
too.
B
A
B
E
C
I
guess
I'm
definitely
excited
about
it
and
it
means
I'm,
gonna,
I,
guess
I'm
gonna
crack
the
whip
on
what's
being
developed
in
the
simulation
branches.
I,
don't
know
if
now's
the
time
to
talk
about
it,
I
just
I
was
hoping.
If
there
was
ever
is
there
kind
of
like
a
place
where
we're
gonna
hit
with
development
of
the
DC
stuff
and
the
potential
field
stuff
there
we
go.
Okay,
we've
accomplished
this
list
of
things:
let's
bring
it
into
the
base
simulation
branch,
I
guess.
C
A
A
A
Fair,
but
are
there
I
think
to
Devon's
points
like
if
we
can
set
some
explicit
goals
like
yes,
it'll,
never
I
mean
there's
lots
that
we
can
continue
to
do,
but
it
also
it
doesn't.
We
don't
have
to
have
like
everything
parallelized
and
everything
like
we
don't
have
to
have
the
entire
sort
of
wish
list
accomplished
before
we
say
that
you
know
the
simulation
class
has
been
plugged
in
it's
running
the
api's
match
good
enough.
We
will
keep
pushing
forward
after
that.
C
Yeah
I
guess
that
yeah,
that's
sort
of
exactly
my.
My
point
is:
there's
all
sorts
of
awesome
stuff,
that's
getting
developed,
but
then
our
beacon
as
make
its
are.
We
gonna
make
it
so
we
can't
run
a
basic
gravity
forward,
modeling
because
we
really
want
to
get
to
parallelizing
a
particular
problem
like
where
we're
keeping
I
know
I
have
a
feeling
that
we're
keeping
some
of
these
these
tools
that
are
fairly
straightforward
from
people,
because
it's
it's
part
of
a
branch
where
there's
continuous
development,
but
we
have
a
whole
bunch
of
stuff
that
actually
works.
C
A
Yeah,
that's
that's
an
important
point
Devon
in
terms
of
like
the
simulation
branch
itself,
and
maybe
this
is
also
a
way
to
square.
Some
of
this
dome
is,
if
we
get
I,
can
take
a
look
at
where
that's
at
it's
been
a
while
since
I've
had
time
to
touch
that,
but
I
can
try
and
spend
some
time
this
week.
Looking
at
basically
had
we
ported
the
API
and
I.
Think
that's
to
Devon's
point
I!
Think
that's
a
good
good
check.
A
C
E
C
I
guess
I
have
a
little
bit
of
a
wish
list,
probably
even
more
basic
than
what
you
guys
are
working
on,
which
is
really
just
with
all
the
new
simulations
I
would
like
to
be
able
to
run
a
you
know
forward
modeling
example
for
gravity
magnetic,
maybe
Grady
arbitrary
example
of
those
dcpip
Fe
em.
Just
you
know,
be
able
to
do
that.
That's
stuff!
This
is
one
set
of
tasks.
That
I
think
is
a
pretty
good
benchmark
for
being
able
to
add
new.
F
A
A
Cool
yeah
and
I
think
and
actually
Devon.
This
might
even
be
a
good
place
to
start
is
planning
out
the
utils
refactor.
That
gives
us
a
fairly
concrete
thing
and
something
that
hasn't
hasn't
been
done,
but
that's
something
that
I'm
happy
to
jump
in
and
like
help
provide
a
little
bit
of
guidance
just
just
to
like
sort
of
order
of
operations
and
Dom
I'm
sure
has
some
ideas
there
too.
A
So
that
might
be
a
good
place
to
like
test
test
out
creating
a
project,
and
then
we
can
start
doing
that,
because
this
chameleon
one
is
going
to
be
a
bit
more
challenging
and
require
some
conversations.
So
if
you
get
sort
of
like
the
infrastructure
in
place
for
something
that's
a
little
easier,
that
might
be
a
nice
way
to
go.
Yeah.
C
G
C
Cruise
tills,
in
kind
of
the
correct
way,
and
then
we'll
do
them-
you
could
move
them
where
we
wanted
them,
so
you
could
basically
just
say
from
utils
call
make
effect
and
it
could
live
somewhere
down
down
the
line
in
that
parent
parent
directory,
but
that
it
could
just
be
called
say
from
utils.
Give
me
this.
That
was
I.
Think
that
was
sort
of
the
idea
did
I
get
that
right
done.
Yeah
yeah.
A
So
at
this
point,
I
would
actually
say
start
from
the
simulation
branch.
Don't
don't
worry
about
starting
from
master
yeah
I
think
that'll
be
a
bit
simpler,
but
yeah,
and
then,
if
you,
if
you
write
sort
of
write
those
steps
down,
then
we
can.
We
can
don't
flush
that
out
in
a
little
bit
more
detail
just
so
that
it's
like
becomes
a
bit
more
of
a
checklist
rather
than
sort
of
open
question
marks
and
things
that
we
think
through
a
pull
request.
B
B
I've
been
asked
to
give
a
talk
at
round
up
in
their
forums
talking
about
tkc,
and
this
would
be
to
primarily
to
geologists.
So
it's
it's
an
opportunity
for
us
to
kind
of
reinforce
the
potential
benefits
of
doing
advanced
geophysical
analysis.
You
know
before
they
drill
too
much
and
frankly,
I
was
totally
aghast
when
I
realized
that
it
was
September
2015
four
years
ago
that
we
had
the
symposium
that
brought
in
all
of
these
different
groups
of
people,
and
we
talked
about
you
know
what
we'd
been
doing
at
tkc
and
the
3d
inversion.
B
B
A
B
We
can
we
do
something
about
that,
estimating
the
volumes
and
then
you
know,
went
back
and
looked
at
the
presentations
and
you
know
sure
enough
soggy
and
had
a
3d
volume,
a
litera
and
Dom
with
classifications
and
yeah.
So
we
don't
want
to
forget
things
and
we
just
want
to
you
know,
add
some
new
stuff
and
really
try
to
put
together
a
really
nice
story
and.
A
B
I
think
that
start
off
with
maybe
just
some
kind
of
a
Google
Doc
in
which
we
try
to
put
down
okay.
What
were
the
geologic
questions
that
was
there
try
to
capture
what
the
history
was?
The
you
know
of
the
geology,
Sarah
and
Chris
did
a
pretty
good
job.
I
mean
at
one
point:
I
I'd,
read
all
those
papers
and
kind
of
had
a
pretty
good
idea,
and
that's
just
totally
gone
I
mean
I.
Just
can't
remember
this,
so
it
might
be,
might
be
worthwhile.
Do
you
know
put
a
few
of
these
things?
