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 .m³ / s K) (1 1 -3 -1) .


But in solveSolid.H:


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


here K should be the Thermal Diffusivity (DT). (m²/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)
);
