Summary0001108: Bug in externalWallHeatFluxTemperatureFvPatchScalarField
DescriptionI Believe something may have gone wrong in the updated implementation of externalWallHeatFluxTemperatureFvPatchScalarField (line 256-268 of the .C file).

The heat flux is now calculated as:

 scalar totalSolidRes = 0.0;
        if (thicknessLayers_.size() > 0)
        {
            forAll (thicknessLayers_, iLayer)
            {
                const scalar l = thicknessLayers_[iLayer];
                if (l > 0.0)
                {
                    totalSolidRes += kappaLayers_[iLayer]/l;
                }
            }
        }
        q = (Ta_ - Tc)/(1.0/h_ + totalSolidRes);

I believe the resistance should be calculated as kappa/l, rather than its inverse?
In the previous version of the code (only single layer), this effectively has been the case, i.e.

        q = (Ta_ - Tc)/(1.0/h_ + thicknessLayer_/(kappaLayer_ + VSMALL));
