Hi everybody!

I'm trying to simulate the interface between a porous medium and a fluid, for a natural convection problem.
I've two different domain and I have to set the interface between them.

The problem is that I have temperature anomalies at the interface that are not realistic (like -20°C when I'm working with temperatures close to 0°C).
I've tried to refine the mesh at the interface and to change the interface type...but nothing...

Do you have some suggestions?

Thank you very much!!
Barbara
