Hi yt-users, I'm trying to play around with yt for SPH type data (there's no frontend for this code). I found out how to load generic particle data via the load_particle_data stream (http://yt-project.org/docs/dev/examining/generic_particle_data.html#generic-...) and I found some information on SPH type data (http://yt-project.org/doc/analyzing/fields.html#sph-fields) but I can't seem to figure out how to tell yt that I have a smoothing length and a particle I want to smooth. Is there a way to do this? I attach a non-working script showing roughly what I'm trying to do. Thanks in advance! Best, Jonah
