Hello everyone,

I am looking through the heat transfer tutorials in OpenFOAM, more specifically the simpleCarSolarPanel. I would like to know if the solarpanel patch can be specified to heat-up due to radiation.

I changed the zeroGradient bc to externalWallHeatFluxTemperature to work in flux mode with q = 0 and qr = qr.

However, the density keeps on decreasing and eventually I end up with "Negative initial temperature".

If I decrease the relaxation factor to 0.1, it will finish the 50 steps of simulation with a temperature on the patch of ~1000K, which is non-physical...

Can buoyantSimpleFoam be used for this? Or do I need to mesh the panel region and move to chtMultiRegion?

Any suggestions?


Best Regards
