Dear All,

There is an error in the resolution of the temperature in the solid part of chtMultiRegionSimpleFoam. In version 1.7.x and 1.6-ext

In the tutorial: K is the thermal conductivity (kg .m / s K) (1 1 -3 -1) .

But in solveSolid.H:

fvScalarMatrix tEqn
-fvm::laplacian(K, T)

here K should be the Thermal Diffusivity (DT). (m/s)

So in the chtMultiRegionSimpleFoam:
It will be better to rename the 0/solid/K → 0/solid/DT and to change solveSolid.H to:

fvScalarMatrix tEqn
-fvm::laplacian(DT, T)
