[yt-users] Enzo Tracer Particle Visualization

[Yuan Li]

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.
