I am trying to solve an unsteady flow throuth porous media which is a SS mesh under non-equilibrium condition.Do I need to define an additional UDS to solve the porous solid surface temperature and susequently redifine the source term for fluid energy equation? Or when I check the non-qulibriem checkbox under the porous tab, fluent automatically solves the porous solid temperature and adjust the heat transfer between fluid and solid as a source term in fluid energy equation?

Non-equilibrium porous media should do what you need - check the documentation and if in doubt build a 2d test model. I assume the casing around the porous zone is well insulated?

Ok thanks. The reason for my question is that in some other CFD forums there were threads regarding adding a UDS for solving the solid temperature in porous zone, but those threads go back to couple years ago and I am not sue if Fluent had the non-equilibbrium solution at that point. So all in all, no additional UDS definition is required for solving the solid temperature in current version of fluent, correct?

Correct, the model's been in the code for a while but I can't remember which release. Current release is 2023R1 soon to be 2023R2.
