Did you consider mass transfer? If not, then you need to write your UDF. This has been asked several time and you will find good information on the Ansys support team.

yes i have consider mass transfer as evaporation and condensation model

Dear Juliom
I have consider mass transfer - evaporation and condensation
heat transfer - two resistance model with zero resistance
i have taken water enthalpy zero. in material prop. bottom with 325 k and and top glass with 320k i want to trap surface evaporation and condensation of that vapor on glass in fluent

Hello people,
I am trying to model a case of a brick considering it as a porous medium, I am using the multicomponent model inside the brick, where I will take into account the evaporation process, but unfortunately I can not get the problem right, can anyone give me some idea ? Can this case be solved in cfd or just not fluent?

thank you

Please explain what you are trying to do, what physics is happening and why you are trying to model this.
