chtMultiRegionFOAM " Heattransfert"
I have tried to simulate an Heat Exchanger using " chtMultiRegionFoam (Air and solid)", but nothing append in the Solid. No heat transfer in the solid.
Could someone give a idea?

I suppose you might not given correct boundary conditions for the fluid and solid interface.

Try to look at the tutorial provided in the chtMultiRegion foam dictionary.

The T at interface should be solidWallMixedTemperatureCoupled. and you should also change the boundary patch to directMappedPatch.

If you do appropriate changes, you should get the temperature variation in solid region also.
