hi: I am researching on particle.I want to write a UDF about particle body force. But the force is relative to particle concentration.I cann`t find the micros of concentration. Who can help to compile the particle concentration. How to write particle concentration of every cell in computational domain.Thanks you very much!

You can get the particle concentration in a cell through the macro C_STORAGE_R(c,t,SV_DPMS_CONCENTRATION)

hi Sujith:

Thank you very much indeed for your favor always!I have been seen this micros before.But i haven`t been known how to use it.Do you have a example about it to go shares with me? Thanks alot!
