[yt-users] smoothed particle velocities onto unigrid

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
