Hello everyone,
recetly ,I still use icoFoam to calculate a channel flow. I use ICEM to generate a struct mesh,Then I use fluent3DMeshToFoam to make the polyMesh dic. But when I run icoFoam,it can not go even one step. It shows; #0 Foam::error:: printStack(Foam::Ostream&) in "/home/wh/OpenFOAM/OpenFOAM-2.1.1/platforms/linuxGccDPOpt/lib/libOpenFOAM.so" #1 Foam::sigFpe::sigHandler(int) in "/home/wh/OpenFOAM/OpenFOAM-2.1.1/platforms/linuxGccDPOpt/lib/libOpenFOAM.so" #2 Uninterpreted: #3 void Foam::fvc::surfaceIntegrate<double>(Foam::Field<do uble>&, Foam::GeometricField<double, Foam::fvsPatchField, Foam::surfaceMesh> const&) in "/home/wh/OpenFOAM/OpenFOAM-2.1.1/platforms/linuxGccDPOpt/bin/icoFoam" #4 Foam::tmp<Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh> > Foam::fvc::surfaceIntegrate<double>(Foam::Geometri cField<double, Foam::fvsPatchField, Foam::surfaceMesh> const&) in "/home/wh/OpenFOAM/OpenFOAM-2.1.1/platforms/linuxGccDPOpt/bin/icoFoam" #5 Foam::tmp<Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh> > Foam::fvc::div<double>(Foam::GeometricField<double , Foam::fvsPatchField, Foam::surfaceMesh> const&) in "/home/wh/OpenFOAM/OpenFOAM-2.1.1/platforms/linuxGccDPOpt/bin/icoFoam" #6 Foam::fv::gaussLaplacianScheme<double, double>::fvmLaplacian(Foam::GeometricField<double, Foam::fvsPatchField, Foam::surfaceMesh> const&, Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh> const&) in "/home/wh/OpenFOAM/OpenFOAM-2.1.1/platforms/linuxGccDPOpt/lib/libfiniteVolume.so" #7 Foam::fv::laplacianScheme<double, double>::fvmLaplacian(Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh> const&, Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh> const&) in "/home/wh/OpenFOAM/OpenFOAM-2.1.1/platforms/linuxGccDPOpt/lib/libfiniteVolume.so" #8 in "/home/wh/OpenFOAM/OpenFOAM-2.1.1/platforms/linuxGccDPOpt/bin/icoFoam" #9 in "/home/wh/OpenFOAM/OpenFOAM-2.1.1/platforms/linuxGccDPOpt/bin/icoFoam" #10 in "/home/wh/OpenFOAM/OpenFOAM-2.1.1/platforms/linuxGccDPOpt/bin/icoFoam" #11 __libc_start_main in "/lib/libc.so.6" #12 in "/home/wh/OpenFOAM/OpenFOAM-2.1.1/platforms/linuxGccDPOpt/bin/icoFoam" Floating point exception (core dumped) |
