Hi Foamers,
for a parallel simulation of a naca0021 on a bluff angle (DES-LL hybrid scheme) with a periodic boundary condition on the front and back, a fixed value inlet and zero gradient outlet the system produce this error message on a end of a Timestep: Foam::sigFpe::sigFpeHandler(int) in "/usrfem/femsys_local/OpenFOAM/OpenFOAM-1.6/lib/linux64GccDPOpt/libOpenFOAM.so" THE SYSTEM IS STABLE FOR A COUPLE WEEKS !!! From the forum I know also thats this error message are a random error. The most suggestions to fix this problem floatTransfer=0, unfortunately not work. The OpenFOAM system is installed on a suse 10 the simulation crash on suse 10 and also for a suse 11 system, but not at the same time (bit later). Also the try to compile the solver on both machines (suse 10/11) doesn't work. I'm not sure how I can handle this problem,? The last thing is to run on a single core or a new decompose. Hope for a clue to save this simulation. Thank you for your help ! best regards Sven |
