Hello guys! I'm currently trying to simulate the flow around the onera -m6 wing. the flow is compressible and I'm using the Spalart-Allmaras turbulence model. The grid I'm using is hybrid.

My main problem is that I'm bumping onto the same error which is the following:

I'm monitoring the residuals and even though they've reached a good order of accuracy for the complexity of the grid (10^-4 for pressure and 10^-5-6 for velocity). the solution hasn't converged. I'm also using rhoSimpleFoam solver.

From the error that i get i understand that something occurs within the thermophysicalProperties File, however i don't understand what it is. I would be very grateful if someone has a tip to give me or an idea of what could be going wrong.
