Hi everybody.

Who knows how I can define the best heat transfer boundary condition for a surface between two zones, for example solid/fluid or solid/solid?

I have already generated the geometry and mesh file of two zones, but I can't apply B.C. to the interface wall.

thnx

You can add something to the interface boundary (fluid/solid).
There you can define a "heat generation rate" boundary. I think, you can use UDF to define this value, if it is not constant.

I want to simulate a geometry like this:
