huopao is on a distinguished road
I am trying to write a short UDF to simulate "coal particle reaction" , as the calculation zone set as porous medium, so should I calculate the gas product source term by " / (C_VOLUME(c,t) * CURRENT_TIMESTEP", or " /(porosity * C_VOLUME(c,t) * CURRENT_TIMESTEP" which consider the source term only produce in gas phase.

Thank you very much!

I seems have an answer to my confusion, it seems that the source term defined by "per unit volume of cell per time".
