problem when running icoFoam on a complex shape flow field
Hi,
I am asking a question about running icoFoam on a complex shaped 3D flow field(I sHM it ). when I run icoFoam on the case, I got the following information #0 Foam::error::printStack(Foam::Ostream&) in "/home/xhw/OpenFOAM/OpenFOAM-1.5/lib/linuxGccDPOpt/libOpenFOAM.so" #1 Foam::sigFpe::sigFpeHandler(int) in "/home/xhw/OpenFOAM/OpenFOAM-1.5/lib/linuxGccDPOpt/libOpenFOAM.so" #2 Uninterpreted: [0xb7ffe400] #3 Foam::PBiCG::solve(Foam::Field<double>&, Foam::Field<double> const&, unsigned char) const in "/home/xhw/OpenFOAM/OpenFOAM-1.5/lib/linuxGccDPOpt/libOpenFOAM.so" #4 Foam::fvMatrix<Foam::Vector<double> >::solve(Foam::Istream&) in "/home/xhw/OpenFOAM/OpenFOAM-1.5/applications/bin/linuxGccDPOpt/icoFoam" #5 Foam::lduMatrix::solverPerformance Foam::solve<Foam::Vector<double> >(Foam::tmp<Foam::fvMatrix<Foam::Vector<double> > > const&) in "/home/xhw/OpenFOAM/OpenFOAM-1.5/applications/bin/linuxGccDPOpt/icoFoam" #6 main in "/home/xhw/OpenFOAM/OpenFOAM-1.5/applications/bin/linuxGccDPOpt/icoFoam" #7 __libc_start_main in "/lib/tls/i686/cmov/libc.so.6" #8 _start in "/home/xhw/OpenFOAM/OpenFOAM-1.5/applications/bin/linuxGccDPOpt/icoFoam" Floating point exception To keep the courant number <=1 , I defined the deltaT=0.005 according to velocity , cell size , But the courant number becomes Courant Number mean: 1.15107e+98 max: 1.04117e+102 when T=0.08 the attachment is the case files Anybody can give me some hints? Thank you very much for any help. Wendy |
