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 ...

mpirun noticed that job rank 0 with PID 24755 on node localhost exited on signal 8 (Floating point exception).

2) simpleFoam > log &
runs smoothly without a problem.

Initial U conditions:
... snip ...
internalField uniform (9.9756 0.6976 0);

boundaryField
{
wall
{
type fixedValue;
value uniform (0 0 0);
}
pressure-far-field-1
{
type fixedValue;
value uniform (9.9756 0.6976 0);
}
... 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 &
