Hello!

I need to analyse a 2D (axial) cross section of a dual pipe heat exchanger for a multiphase heat transfer problem.

I created the geometry on DM using sketches and surfaces - but I'm facing an issue with the walls: I need shadow regions created so that I can enable coupled heat transfer between the walls. I have explicitly specified multiple (fluid, solid, fluid) for the inner pipe region, pipe wall and the annulus.

Any way I can manually add a shadow region or get FLUENT to recognize that this wall is an interface between a solid and fluid?

Thanks!
