I am trying to use DEFINE_SOURCE macro to define a enthalpy source in porous zone. I know for enthalpy source terms caused by chemical reactions, fluent will multiply this source term by porosity. I am wondering if I have a user defiend enthalpy source term say Hg. Will fluent multiply this term Hg with porosity? If I want fluent use Hg in energy equation, should I return Hg/porosity in DEFINE_SOURCE macro so that the final utilized source term is Hg?

You need to take care about that and do the multiplication on your own.

Do you mean I should multiply Hg with 1/porosity in DEFINE_SOURCE macro?

IF you want to a define a source applied in a volume and that volume is a porous volume you should multiply the source term with porosity.

Thanks very much!
