[yt-users] Particle Density Projection for Flash Data

Dear all,

I have just started using yt3 and would like to display particle densities
in a projection plot.

It seems that for Enzo data, I can use ('deposit', 'io_density'). With
Flash data, however, dd['deposit', 'io_density'] will give me an error
message:
KeyError: "Unable to open object (Object 'particle_posy' doesn't exist)"

I have checked and the particles are there. dd['io', 'particle_posy'] does
return the particle y positions, so I am confused. Are there other ways of
projecting particle densities for Flash data?


Thank you!
Yuan
