Hi all,
I am running into this weird hitch when trying to run simpleFoam parallel on a NACA 0012 subsonic airfoil for an AoA different from 0: 1) mpirun -np 2 simpleFoam > log & stops with error at the fifth iteration apparently with a fpe: mpirun -np 2 simpleFoam -parallel > log [0] #[1] #0 Foam::error:rintStack(Foam::Ostream&)0 Foam::error:rintStack(Foam::Ostream&) in "/home/pier/Open in "/home/pier/OpenFOAM/OpenFOAM-1.5/lib/linuxGccDPOpt/libOpenFOAM.so" [1] #1 Foam::sigFpe::sigFpeHandler(int)FOAM/OpenFOAM-1.5/lib/linu in "/home/pier/OpenFOAM/OpenFOAM-1.5/lib/linuxGccDPOpt/lixGccDPOpt/libOpenFOAM.so" [0] #1 Foam::sigFpe::sigFpeHandler(int)bOpenFOAM.so" [1] #2 Uninterpreted: [0xffffe400] ... snip ...

Thanks for any hint on this, Pier |

U should write:
mpirun -np 2 simpleFoam -parallel > log & or nohup mpirun -np 2 simpleFoam -parallel > log & |
