Hi all, I am trying to make projection plots (e.g. average particle temperature) using Enzo tracer particles. Is there a way of doing this using yt? Thank you!

I think so. Don't enzo tracer particles have a different particle type than non-tracers? If so, you should be able to make a Particle Filter using that particle type and then use the corresponding deposit fields to do the Projection. See this for more information: http://yt-project.org/docs/dev/analyzing/filtering.html#filtering-particle-f... On Mon, May 18, 2015 at 1:35 PM, Yuan Li wrote:

Hi Cameron, The particle fields only include particle positions and velocities, but not tracer particle temperatures for example. Depending on how well the particles trace the fluid, a particle temperature map can look a bit different from a gas temperature map. I can make particle temperature maps using numpy histogram2d, but was hoping to be able to do it in yt for more direct comparisons. For now, my particle maps look fairly similar to the gas maps made using yt, but the ranges can be a bit different. Yuan On Tue, May 19, 2015 at 1:32 PM, Cameron Hummels wrote:

Hi Yuan, I am interested, but have little knowledge about your problem. The particle fields in the HDF5 file don't contain the tracer particle temperature, or yt is not able to read the temperature information that is in the HDF5 file? -Stephanie -- Dr. Stephanie Tonnesen Alvin E.

Hi Stephanie, There is temperature information stored in TracerOutput* files, which allows me to make temperature maps of the particles without yt. I used to assume that yt would automatically read in all the tracer particle information, but maybe I was wrong. Maybe the TracerOutput* files is a whole separate thing. Or yt does read in everything, but does not process some of the information, such as temperature and density? I am not sure. Yuan On Tue, May 19, 2015 at 2:52 PM, Stephanie Tonnesen wrote:

Hi Yuan, It won't work automatically with Enzo outputs, but you can use load_particles() to get each output as its own dataset. -Matt On Tue, May 19, 2015 at 2:08 PM, Yuan Li wrote:
