Dear FOAMers

I'm new in OpenFoam and would like to model steady state conjugate heat transfer(solid and fluid region) in a heat exchanger which consists of a few vertical metal plates attached to a horizontal plate with fluid flowing in gaps between plates.

My current experience with OpenFoam is restricted by “Lid-driven cavity flow tutorial” and “Stress analysis of a hole” tutorials. I know that there are “chtMultiRegionFoam” and “chtMultiRegionSimpleFoam” cases in /tutorials/heatTransfer/ folder. However, i didn't findt tutorials which would explain these cases and it's hard to understand what is going on in these cases without explanation.

I wonder if there is a step-by-step tutorial similar to “Lid-driven cavity” tutorial explaining conjugate heat transfer.
I also wonder if there are tutorials explaining
- how to create a case containing regions with different properties(fluid and solid), assign regions and boundaries;
- how to use conjugate heat transfer solvers;

My next step will be to model a steady state conjugate heat transfer in a porous material consisting of orthogonally interlaced cylindrical wires and fluid between them. I have a geometry for this case created in Abaqus.

I wonder if there is any way to translate my geometry from Abaqus to Open Foam preserving surfaces and regions definitions. Or what would be appropriate tool consistent with Open FOAM where I can create such geometry and define regions and surfaces?

Thank you!
