[yt-users] Generation of smoothing lengths from coordinates of tracer particles

[Amos Manneschmidt]

Hello,

I am a student researcher working on the Chimera project. Part of my work involves creating density maps from tracer particles that accurately represent what we get directly interpolated to the grid from chimera code. If I can do this I know I can make accurate element abundance maps for up to 150 species. We are limited by computing resources to creating maps for only 14 species directly. 

Here is a video of the best conservative density plot I have been able to come up with thus far. The smoothing lengths for the tracers are found in a round-about way right now that is less than ideal. Is there a way in yt to create smoothing lengths using just particle coordinates like this? (IE the complex nearest neighbor math I would rather not code myself if I don’t have to)


Thanks,

Amos M
