DPM concentration
 
Dear all, I would like to get the concentration (kg/m3)of injected (inert) particles for each cell. In the user manual, there are only a few notes on particle concentration in the field variable list, but nothing on how to get it. In the UDF manual, there is nothing. I got a UDF example from somebody where this line appears:

qm3=charge_mass*C_STORAGE_R(c,t,SV_DPMS_CONCENTRAT ION);

Could please somebody explain me the meaning and the usage of the C_STORAGE_R and SV_DPMS_CONCENTRATION functions? C_STORAGE_R appears once in the manual but without expalanation. Thank you, Szabolcs

Re: DPM concentration
 
this is to allocate the memory in order to be able to use the DPM_CONCENTRATION macro.

Hope this help

Hi Szaboles Varga,

I am wondering if you could solve the problem of calculating dpm concentration. I have to calculate it amd I do not know how I should use C_DPM_CONCENTRATION(c,t) macro exactly,

I will be grateful if you can help me

Bests,
