Hello all,

I have a quick question about specifying a thermal boundary condition. Is there a possibility to define a linearly increasing heat flow at a surface?

As shown schematically in the picture, I want to specify a heat flux at a surface (nozzle) which increases linearly from left to right.

Or do I have to divide the total surface into individual segments and specify the gradient on each sub-surface accordingly?

Thank you very much for your help.

With kind regards

Hi Basti,

You may get this working using expressions in OpenFOAM versions from ESI.
