Hi!

I am interested in the chtMultiRegionFoam solver. In fact I don't need the fluid part of this solver since (for the moment) I only need to simulate the diffusion of fields trough 2 motionless regions.

So in my simulations I only set up 2 solid regions and 0 fluid region.

I wonder how the interface between the 2 solid regions is treated ? Is the solidWallMixedTemperatureCoupled BC is suitable ?

Moreover, I don't understand why the Diffusion coefficient, the density and the heat capacity as considered as variable fields ? If it is really that, it is possible to simulate my problem with the laplacianFoam solver and a diffusion coefficient field whom the value depends on the region ?

Thank for your clarifications

Ok! I have a answer to my questions ! I just modified the laplacianFoam solver : I declared the diffusivity DT as a variable scalarField and then I patched this field with different value according to the region.

It is an easiest way than the chtMultiRegionFoam solver and it works well for my applications.
