I am trying to perform simple 2D CFD analysis on Fluent having 3 adjacent zones(inlet, porous and outlet).
The problem I have is whenever I select non-equilibrium thermal model in porous zone in Cell Zone Conditions (as follows)
I get the following error:
A duplicate of this zone cannot be generated automatically, as it contains a non-conformal mesh interface.
You must manually make a copy the porous fluid zone and define it as a solid zone before you enable the non-equilibrium thermal model.
AFAIK, a non-conformal mesh interface is an interface which does not have equal number of nodes on both sides, but it seems to me (visually) that I have an equal number of nodes on both sides (between zones):
So how can I make sure that I have conformal mesh interface between the fluid zones and the porous zone?
