[yt-users] Improve streamline plot

Dear yt: How do I adjust the line width and color for streamline plots? Drive link to streamline plot (streamlines_t000.png) and the script (yt_streamline.py) is below. I also checked the yt link below but it does not seem to have options for line width and line color. Thanks in advance https://drive.google.com/open?id=0B4g8shg4DL7oak5PLWVVdG5UMHc http://yt-project.org/doc/reference/api/generated/yt.visualization.streamlin...

Ooh, slick! Thank you again!

cd $HOME hg clone https://bitbucket.org/MatthewTurk/hgbb

create or edit your $HOME/.hgrc to contain:

[extensions] hgbb = $HOME/hgbb/hgbb.py

Then you'll be able to do the following in your local clone of yt repo:

hg bbpr # will give you list of PRs hg bbpr -p 2066 # would download incoming changes and suggest rev # to update to

Cheers, Kacper

Hey All,

I'm having some trouble smoothing particle velocities onto a uniform (arbitrary_grid) grid. The basic idea is that I create an arbitrary grid, then want to access the particle quantities smoothed onto that grid. Some are relatively easy, like:

mass = obj[('deposit','PartType0_mass')].in_units('Msun')

and for others, where deposited fields don't already exist, I can create those fields and it all works well:

ds.add_deposited_particle_field(('PartType0', 'Temperature'),'sum') temp = obj[('deposit', 'PartType0_sum_Temperature')]

but when either trying to access a deposited particle field, or creating one with the velocities, errors are abound. I'm sure I'm just doing something foolish, but could use a little nudge in the right direction. I created a self-contained script using the gadget zoom data set on the yt datsets to show the problem, with two different error messages pastebinned (links in the script) here:

http://paste.yt-project.org/show/6352/

any help would be greatly appreciated!

thanks, desika -------------- next part -------------- An HTML attachment was scrubbed... URL: < http://lists.spacepope.org/pipermail/yt-users-spacepope.org/attachments/2016...

Hi, I am having troubles using the smoothed_covering_grid and covering_grid with RAMSES dataset. I have yt-project version 3.2.3 and I am using the "output_00080" dataset from the yt sample datasets.

smoothed_covering_grid fails (raising a RuntimeError because tot != 0, line 880 of construction_data_containers.pyc), while covering_grid seems to leave unfilled the refined regions. What I mean is that if a cell is refined beyond the maximum allowed level for the grid, it is left unfilled (contrary to what happens with ENZO datasets).

I am using this code:

import yt import matplotlib.pyplot as plt

ds = yt.load('/users/egaraldi/Documents/output_00080/info_00080.txt')

cgrid = ds.covering_grid(0, left_edge=ds.domain_left_edge, dims=ds.domain_dimensions)

density_field = cgrid["density"]

print (density_field == 0.0).any() #should be False but it is True

plt.imshow(density_field[:,:,48].v, interpolation='none') plt.show() ? #holes with zero-density corresponding to refined regions

Am I doing something wrong?

Thanks in advance, Enrico

Hi Enrico,

I don't think you're doing anything wrong - this is a bug, likely a generic issue with the way covering grids get filled out for octree data.

This issue with smoothed_covering_grid is likely another, different but related bug.

Can you create an issue to track this?

Hi Nathan, thanks for the feedback. I will create the issue right away.
