Solid-Fluid Interface chtMulti

Hi all,

I have just a question to the Interface between coupling solid-fluid or solid-solid Interfaces with the cht solver.

If I want to calculate the heat-transfer between two solids the Interface is handled as a perfect Interface with exact Connections.

In the reallity we have roughtness between the Interface which causes not perfect heat-transfer areas. So the question is if it is possible to represent this physic with a BC or so on - maybe Groovy - ?

Has someone any experiance with that?

Thanks in advance.
Tobi

If you were to solve this problem in 1D, with pen&paper, how would you do it?
