hello,
I tried to do a simpleFoam in OpenFoam-1.5. But when I did main commands, I've got a mistakes. Well, I don't know openFoam, I don't know linux well, but please, if you know where I am wrong, say me. Here is what I have seen in terminal:
#0 Foam::error:rintStack(Foam::Ostream&) in "/opt/OpenFOAM//OpenFOAM-1.5/lib/linux64GccDPOpt/libOpenFOAM.so"
#1 Foam::sigFpe::sigFpeHandler(int) in "/opt/OpenFOAM//OpenFOAM-1.5/lib/linux64GccDPOpt/libOpenFOAM.so"
#2 ?? in "/lib/libc.so.6"
#3 Foam::PBiCG::solve(Foam::Field<double>&, Foam::Field<double> const&, unsigned char) const in "/opt/OpenFOAM//OpenFOAM-1.5/lib/linux64GccDPOpt/libOpenFOAM.so"
#4 Foam::fvMatrix<Foam::Vector<double> >::solve(Foam::Istream&) in "/opt/OpenFOAM//OpenFOAM-1.5/applications/bin/linux64GccDPOpt/icoFoam"
#5 main in "/opt/OpenFOAM//OpenFOAM-1.5/applications/bin/linux64GccDPOpt/icoFoam"
#6 __libc_start_main in "/lib/libc.so.6"
#7 Foam::regIOobject::readIfModified() in "/opt/OpenFOAM//OpenFOAM-1.5/applications/bin/linux64GccDPOpt/icoFoam"

example what I try to do is described in programmersguid on P-54. I did blockMesh, which has done without any problems. But when I tried to do icoFoam I had that mistake.

This exercise is about simpleFoam. You seem to be running icoFoam.

Well, at first I did blockMesh. Then icoFoam, This mistakes appeared after icoFoam, It did 34 steps. Then it said, that courant is something about 123e+129. It's abnormal...

Arina, what Martin tried to say is that the tutorial isn't supposed to be run with icoFoam, but simpleFoam. So it's no surprise icoFoam doesn't converge. Try using simpleFoam instead.

Hello.

Now I have a new problem. I tried to run parafoam and saw a mistake:
paraview: pthread_mutex_lock.c:87: __pthread_mutex_lock: Assertion `mutex->__data.__owner == 0' failed.
Aborted

Why has it appeared? And what is better to do?
