Re: [yt-users] Fwd: smoothed particle velocities onto unigrid

Hi Alex, Desika I think the issue is that add_deposited_particle_field doesn't support vector fields. FWIW, there are already deposited velocity fields for each of the velocity components defined for that dataset. See: https://bpaste.net/show/3f6d25193a2b -Nathan On Wed, Mar 23, 2016 at 10:57 AM, Alex Hill wrote:

Cheers, Alex

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:

any help would be greatly appreciated!
