Default wallHeatFlux with constAnIso (anisotropic material)

I'm modelling solids with anisotropic heat conductivity using the chtMultiRegionSimpleFoam solver (OpenFOAM 2.3.1). I define e.g.
kappa (20 80 20);
in the thermophysicalProperties dict and the temperature field is calculated correctly. However, the wallHeatFlux utility gives wrong results because it seems to use the magnitude of kappa ((20^2+80^2+20^2)^0.5=84.9).

Does anybody have an idea what to change in wallHeatFlux in order to use the specific kappa value which is valid for each patch depending on its direction?

Best regards,

Hi Hugo,

OpenFOAM newbie here. I'm trying to do the same thing (using the same solver in a problem where a material has anisotropic thermal conductivity).

First of all, I hope you solved your problem!

How did you define the three values in the thermophysicalProperties dict?

Thank you,
