Hi Dr Amine What do you mean? Do you mean to say that I need to correct the expression real mf_vapor =C_YI(c,t,0) ; to account for a phase instead of a mixture ? In my model I have defined h20 as a phase in a mixture of air and h20 through species transport model. So I dont exactly understand what you meanthttps://forum.ansys.com/discussion/comment/99119#Comment_99119

Yes what you defining is wrong. You need to read the Customization manual and get acquainted to the multiphase multi-threading. Mass Fraction is defined as Phase Property so the passed cell thread should be the phase level cell thread and mixture level thread.n
