Mailman 3 Volume render - yt-users

Nov. 21, 2016

      Dear yt:

I am using volume render to visualizing the gradient in field lines.
Is there a way that I can add more sensitivity, in terms of colors to my
final image? Currently the gradient seems very limited and cannot
differentiate between near and far fields. Drive link is below

Thanks in advance

Hi Rahul,
I can confirm that this is a bug with multiplot_yt.  I'll get back to
the list once I find a fix.  In the meantime, can you create an issue on
bitbucket?
Thanks,
John

Hi,
After doing

    from yt.visualization.eps_writer import multiplot_yt
    s = yt.SlicePlot(ds, "z", ["density","temperature",

This works for me
eps_fig = eps.single_plot(s)
    eps_fig.save_fig('zoom', format='eps')
    eps_fig.save_fig('zoom-pdf', format='pdf')
*But, the code below doesn't work for me; error is "YTFieldNotFound:

s.set_width(2.e9, 'cm')
    eps_fig = eps.multiplot_yt(2, 2, s, bare_axes=True)     #not working
now
    #eps_fig.scale_line(0.2, '5 kpc')
    eps_fig.save_fig('multi', format='eps')
Any help would be appreciated, Thanks

Hi again,
The fix was easier than I thought.  Can you test it out?  If you
installed yt with "INST_YT_SOURCE=1" in the install script, then you can
issue the following commands in the yt source directory
hg pull -u -r 9373defa8ed5 https://bitbucket.org/jwise77/yt
python setup.py develop
and see if your script now works.  It works for me with a similar script
as you posted.
If you're using the conda installation, then you can follow the
instructions in this previous email.

Let us know what you find.
Thanks,
John

Hi people,
I wanted to to get slices for temperature and temperature gradient
magnitude setting the maximum temperature at the center. I used yt's
feature:
v,c = pf.h.find_max('temperature') #set center at max_temp
and got the slices, however, my slice outputs clearly show the maximum
temperature was not set at center. I am sharing the python code for the
slices and also my output files.
this code worked when I created density slices and max_dens was set at
center, I don't see it isn't working out for temperature. Thanks for your
help
