Summary0002302: wallHeatFlux utility: wrong calculation of heatfluxes using anisotropic kappa
DescriptionThe wallHeatFlux utility calculates wrong heat-fluxes if anisotropic kappa for heSolidThermo is used.

It seems that the kappa is calculated with kappa = sqrt(kappa1^2 + kappa2^2 + kappa3^2) instead of using the normal-component of the surface.

Also it would be nice if wallHeatFlux could be used like a function object.
Steps To ReproduceIn the multiRegionHeater tutorial use anisotropic kappa (80 80 80) instead of kappa 80 and change the kappaMethod to directionalSolidThermo in the relevant boundary conditions. Using wallHeatFlux utility now calculates wrong heatfluxes.

In OpenFOAM-dev:

dm(201) wallHeatFlux
wallHeatFlux has been superceded by the '-postProcess' solver command-line option, e.g.
simpleFoam -postProcess -func wallHeatFlux

Resolved in OpenFOAM-dev provided the anisotropy is aligned with the boundary.
