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: [2] #0 Foam::error: ![]() [2] #1 Foam::sigFpe::sigHandler(int) at ??:? [2] #2 ? in "/lib/x86_64-linux-gnu/libc.so.6" [2] #3 ? in "/lib/x86_64-linux-gnu/libm.so.6" [2] #4 Foam::hePsiThermo<Foam: ![]() ![]() ![]() [2] #5 virtual thunk to Foam::hePsiThermo<Foam: ![]() ![]() ![]() [2] #6 Foam::solvers::fluid::thermophysicalPredictor() at ??:?

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. |
