Sorry for all the questions this week, however I’m working a lot with preCICE this week. I am having some issues with a case I am making. The temperature/heat flux is I think not passed through correctly. I have made a small test case, to check where it goes wrong, however I cannot find it.
The test case is a rotating plate in air. Openfoam is the fluid domain, Nutils is the plate. The models are made axisymmetric (I don’t know if this can cause any of the problems). Since another plate will be added in the real case with another nutils file, I cannot run the program in serial. (In serial it seemed to be more stable), however in parallel the calculation in Nutils seems to blow up. I have used an implicit coupling scheme in an attempt to stabilize the heat flux, however it doesn’t work for the parallel computation. Would you know if there is anything wrong with my communication of Heat fluxes to OpenFOAM? There should be no reason to get unstable right? Since Nutils gets boundary conditions from the OpenFOAM case, which aren’t very weird. I think in the beginning just ambient temperature. Since Nutils solves the case fully it shouldn’t be randomly unstable?
I will post the files below.

Openfoam (where the yellow line is the interface) (Note that this case is axisymmetric, with the symmetry axis on the left part part):
Thank you in advance!
