The unit is kg/m3, what's the different between C_DPMS_CONCENTRATION(c,t) and density? How C_DPMS_CONCENTRATION(c,t) calculate the cell concentration? 2. When a number of particles through the cell in the domain, how can I get the average particle velocities in the cell by UDF? 3. When I use the DPM model calculate the particle trajectory, I want to get the mass of particle by P_MASS(p), why the result is 0? How can i get the mass of every particles?
