Summary0003882: externalWallHeatFluxTemperature Q handled incorrectly
DescriptionIn OF10 the parameter Q for the boundary condition externalWallHeatFluxTemperature is handeled incorrectly:

Parameters q and Q are summed up, but power Q is not transformed to a heat flux before adding it to the sum.
Q should be divided by the area of the patch before adding it to the sum.

See line in github: https://github.com/OpenFOAM/OpenFOAM-10/blob/8d73542293f9f15151181b5ba0c7696e03bb2ad5/src/ThermophysicalTransportModels/derivedFvPatchFields/externalWallHeatFluxTemperature/externalWallHeatFluxTemperatureFvPatchScalarField.C#L307
Steps To ReproduceUse any case with a externalWallHeatFluxTemperature patch.
Set parameter Q to any value, don't set q.
Evaluating heat flux one the patch during simulation shows Q is used as heat flux, not power.
TagsNo tags attached.
