YT Phase Plot Loop
by Nicholas Earl
Hey all,
I am trying to to have yt load up a data set, and then create phase plots with varying weighted fields like the script below.
The problem is that when reaches the 'for item in field' loop, after each image output, the loop starts over instead of continuing to the next field... for instance, the output for a series of numbers representing the images would look like this:
1
1
2
1
2
3
1
2
3
4
etc
I am not quite sure how to remedy this, so I'm hoping someone could point me in the right direction.
Thanks for your efforts!
Nicholas Earl
from yt.mods import * # set up our namespace
#field = ['Temperature','Cooling_Time']
field = ['Cooling_Time','Density','Electron_Fraction','Gas_Energy','H2II_Fraction','H2I_Fraction','HII_Fraction','HI_Fraction','HM_Fraction','HeIII_Fraction','HeII_Fraction','HeI_Fraction','Metal_Fraction','Temperature','Total_Energy','x-velocity','y-velocity']
for n in range(1,402):
#for item in field:
pf = load("DD%04i/DD%04i" % (n,n))
# load dataset
#for item in field:
pc = PlotCollection(pf, center=[1.0, 0.5, 0.5]) # defaults to center at most dense point
for item in field:
#value, position = pf.h.find_max("Density")
#print value, position
pc.add_phase_sphere(10.0, "pc", # how many of which unit at pc.center
["Density", "Temperature", "CellMassMsun"], # our fields: x, y, color
weight="%s" % (item))# don't take the average value in a cell, just sum them up
#print item
pc.save('./denstemp_weighted/%s' % (pf)) # save all plots

problems with yt

Hi,
Also trying to install yt on the same system, but having problems with

coloring grids and change the range of slices
by Wolfram Schmidt
Hi,
I've got two questions:
(1) Is it possible to change the colors of grid boundaries (produced
with the grids callback), preferably, using different colors
corresponding to refinement levels?
(2) Surely, there must be something to specify the x- and y-range
of slices. Where in the documentation is it explained how to do that?
Best regards,
Wolfram

Sorry! That was a careless error on my part. I've just pushed a change (3e99bb6dbb72) that should fix this. Let me know if it doesn't.

Freetype added to yt build system
by Matthew Turk
Hi all,
As of just now, I've pushed a change to add FreeType2 wrappers to yt,
to enable easier image annotation, particularly from volume rendering.
The function is included in yt.mods, and it's called annotate_image.
(It is documented -- "help(annotate_image)".) This should be the
start of much faster image writing.
There may be issues with compilation on your next update, when you execute:
yt instinfo -u
although I have attempted to guess the paths correctly, and all new
installations using the install script will include FreeType2. If you
run into any issues with this change, please email me directly,
off-list.

How to turn on Debugging?
by Chris Malone
Hi,
It's not very well documented - or at least I wasn't having luck finding
mention in the docs - how to properly turn on debugging for yt. After some
time digging through the source, I have found that this is handled through
the *logging* module - a standard module, which I am not (but should be)
familiar with.
Anyhow, I have gathered that I can turn on debugging by adding the following
two lines to my ~/.yt/config file:
[yt]
LogFile = True
LogLevel = 0
Is this the recommended usage? Is there an easier way to turn debugging on
for, say, a single iyt or yt invocation via a command line argument?

Bingo, that worked. Thanks, also, for the reminder to inspect the source for hints :).

With only that change to what I previously sent, I get this...

It appears that for some reason only the first entry of each of the arrays from the grids is being fed into the combine function. The script <http://paste.enzotools.org/show/1411/> outputs <http://paste.enzotools.org/show/1412/>. This sim has 297 grids, which is the size of the ct array in the combine function.
I'm confused...
