Hi Foamers: I am simulating the flow over a stepped spillway using OF version 2.2.0
The flow is simulated using pimpleFoam solver and RANS approach (v2-f model). I did the geometry in Autocad and exported as a stl file. SnappyHexMesh works fine and my mesh is ok. My model runs OK but... when I change the pressure BC in the upper part (surface) from zeroGradient to fixedFluxPressure I have the following error (segmentation fault): PIMPLE: Operating solver in PISO mode Starting time loop Courant Number mean: 0.000814549 max: 0.394101 deltaT = 0.000335796 Time = 0.000335796 DILUPBiCG: Solving for Ux, Initial residual = 1, Final residual = 2.333e-11, No Iterations 2 DILUPBiCG: Solving for Uy, Initial residual = 1, Final residual = 6.42672e-11, No Iterations 2 #0 Foam::error: ![]() #1 Foam::sigSegv::sigHandler(int) in "/opt/openfoam220/platforms/linuxGccDPOpt/lib/libOpenFOAM.so" #2 Uninterpreted: #3 Foam::divide(Foam::Field<double>&, Foam::UList<double> const&, Foam::UList<double> const&) in "/opt/openfoam220/platforms/linuxGccDPOpt/lib/libOpenFOAM.so" #4 Foam: ![]() #5 Foam::fixedFluxPressureFvPatchScalarField::updateC oeffs() in "/opt/openfoam220/platforms/linuxGccDPOpt/lib/libfiniteVolume.so" #6 at gaussLaplacianSchemes.C:0 #7 Foam::fv::gaussLaplacianScheme<double, double>::fvmLaplacianUncorrected(Foam::GeometricFi eld<double, Foam::fvsPatchField, Foam::surfaceMesh> const&, Foam::GeometricField<double, Foam::fvsPatchField, Foam::surfaceMesh> const&, Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh> const&) in "/opt/openfoam220/platforms/linuxGccDPOpt/lib/libfiniteVolume.so" #8 Foam::fv::gaussLaplacianScheme<double, double>::fvmLaplacian(Foam::GeometricField<double, Foam::fvsPatchField, Foam::surfaceMesh> const&, Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh> const&) in "/opt/openfoam220/platforms/linuxGccDPOpt/lib/libfiniteVolume.so" #9 Foam::fv::laplacianScheme<double, double>::fvmLaplacian(Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh> const&, Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh> const&) in "/opt/openfoam220/platforms/linuxGccDPOpt/lib/libfiniteVolume.so" #10 Foam::tmp<Foam::fvMatrix<double> > Foam::fvm::laplacian<double, double>(Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh> const&, Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh> const&, Foam::word const&) in "/opt/openfoam220/platforms/linuxGccDPOpt/bin/pimpleFoam" #11 at pimpleFoam.C:0 #12 in "/opt/openfoam220/platforms/linuxGccDPOpt/bin/pimpleFoam" #13 __libc_start_main in "/lib/i386-linux-gnu/libc.so.6" #14 in "/opt/openfoam220/platforms/linuxGccDPOpt/bin/pimpleFoam" Segmentation fault (core dumped) There are any thoughts you would like to share, thank you in advance JP |
