<br>
Hey All,<br>
<br>
I'm having some trouble smoothing particle velocities onto a uniform<br>
(arbitrary_grid) grid. The basic idea is that I create an arbitrary grid,<br>
then want to access the particle quantities smoothed onto that grid. Some<br>
are relatively easy, like:<br>
<br>
mass = obj[('deposit','PartType0_mass')].in_units('Msun')<br>
<br>
<br>
and for others, where deposited fields don't already exist, I can create<br>
those fields and it all works well:<br>
<br>
ds.add_deposited_particle_field(('PartType0', 'Temperature'),'sum')<br>
temp = obj[('deposit', 'PartType0_sum_Temperature')]<br>
<br>
but when either trying to access a deposited particle field, or creating<br>
one with the velocities, errors are abound. I'm sure I'm just doing<br>
something foolish, but could use a little nudge in the right direction. I<br>
created a self-contained script using the gadget zoom data set on the yt<br>
datsets to show the problem, with two different error messages pastebinned<br>
(links in the script) here:<br>
<br>
<a href="http://paste.yt-project.org/show/6352/" rel="noreferrer" target="_blank">http://paste.yt-project.org/show/6352/</a><br>
<br>
any help would be greatly appreciated!<br>
<br>
thanks,<br>

<br>
Hi,<br>
I am having troubles using the smoothed_covering_grid and covering_grid with<br>
RAMSES dataset.<br>
I have yt-project version 3.2.3 and I am using the "output_00080" dataset<br>
from the yt sample datasets.<br>
<br>
smoothed_covering_grid fails (raising a RuntimeError because tot != 0, line<br>
880 of construction_data_containers.pyc), while covering_grid seems to leave<br>
unfilled the refined regions. What I mean is that if a cell is refined<br>
beyond the maximum allowed level for the grid, it is left unfilled (contrary<br>
to what happens with ENZO datasets).<br>
<br>
I am using this code:<br>
<br>
import yt<br>
import matplotlib.pyplot as plt<br>
<br>
ds = yt.load('/users/egaraldi/Documents/output_00080/info_00080.txt')<br>
<br>
cgrid = ds.covering_grid(0, left_edge=ds.domain_left_edge,<br>
dims=ds.domain_dimensions)<br>
<br>
density_field = cgrid["density"]<br>
<br>
print (density_field == 0.0).any() #should be False but it is True<br>
<br>
plt.imshow(density_field[:,:,48].v, interpolation='none')<br>
plt.show() ? #holes with zero-density corresponding to refined regions<br>
<br>
Am I doing something wrong?<br>
<br>
Thanks in advance,<br>
Enrico<br>

Hi Enrico,<br>
<br>
I don't think you're doing anything wrong - this is a bug, likely a generic<br>
issue with the way covering grids get filled out for octree data.<br>
<br>
This issue with smoothed_covering_grid is likely another, different but<br>
related bug.<br>
<br>
Can you create an issue to track this?<br>
