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
