Compatible BCs for thermally conductive internal wall using chtMultiRegionFoam

JCollins · April 26, 2022, 11:41

I am attempting to use chtMultiRegionFoam to simulate thermal conduction between two materials that are directly connected. I have two regions that share a wall, and I would like to have a simple continuity boundary between them.

The calculatedFvPatchField is not compatible with mapped walls, so I'm struggling to see which BC suits the need.

Have you tried coupled boundary condition ?

Well that seems to have worked. How did you discover this BC and how is it applicable to this case?

Its in tutorials and moreover I have worked with multiregion models.

I searched everywhere for a tutorial showing two solids attached and conducting, but found none.. How did you come across yours?

Kindly look into chtMultiRegionSimpleFoam tutorial. It solves heat conduction equation in the solid domain, where you can use multiple regions (solid or fluid) and connect regions using coupled boundary condition.
For further information, check this forum page:
How to solve a heat conduction between two different solid materials ?
In post no. 8, Mr. Tobi has attached a solver for 2 solid domains. Hope it helps you.
Thank you
