Hello all I'm currently comparing the size/mass distribution for coal particles before and after combustion. I noticed that when I extract the file under "particle tracking", I get a big data file that contains 9 parameters (time, x,y,z position, x,y,z velocity, density, temperature, mass, and colored by...) for the coal particles

Is there a way to change these parameters? (i.e. what if I only want to extract time, mass, and temperature) The file is huge and I don't want to include parameters such as density, x,y,z position... because they take up space

Any help would greatly be appreciated Thanks

have you tried writing a DEFINE_DPM_OUTPUT UDF? I think this is the best way to go.
