I have been trying to get back into using OpenFOAM after being away from it for several months, and I am having some difficulties while using simpleFoam. The case uses the simpleFoam solver set for laminar flow with 1 inlet and 4 outlet boundary conditions.
Attached is a clipped view showing the velocity and pressure magnitudes at the last iteration prior to crashing. The residual plot shows that my p residual was unable to converge at the specified tolerance, and then eventually crashed. Does the error message below indicate anything obviously wrong with the setup of the model or a boundary condition? I am trying to determine if my mesh has issues, or if one of my boundary conditions is erroneous. __________________________________________________ ____________________ Time = 232 smoothSolver: Solving for Ux, Initial residual = 0.448189, Final residual = 0.000520345, No Iterations 2 smoothSolver: Solving for Uy, Initial residual = 0.536472, Final residual = 0.00101717, No Iterations 2 smoothSolver: Solving for Uz, Initial residual = 0.638983, Final residual = 0.00085336, No Iterations 2 GAMG: Solving for p, Initial residual = 0.988656, Final residual = 9.96993e+66, No Iterations 100 GAMG: Solving for p, Initial residual = 0.913884, Final residual = 1.33824e+72, No Iterations 100 #0 Foam::error:rintStack(Foam::Ostream&) in "/opt/openfoam170/lib/linuxGccDPOpt/libOpenFOAM.so" #1 Foam::sigFpe::sigFpeHandler(int) in "/opt/openfoam170/lib/linuxGccDPOpt/libOpenFOAM.so" #2 Uninterpreted: #3 Foam::GAMGSolver::scalingFactor(Foam::Field<double >&, Foam::Field<double> const&, Foam::Field<double> const&, Foam::Field<double> const&) const in "/opt/openfoam170/lib/linuxGccDPOpt/libOpenFOAM.so" #4 Foam::GAMGSolver::scalingFactor(Foam::Field<double >&, Foam::lduMatrix const&, Foam::Field<double>&, Foam::FieldField<Foam::Field, double> const&, Foam::UPtrList<Foam::lduInterfaceField const> const&, Foam::Field<double> const&, unsigned char) const in "/opt/openfoam170/lib/linuxGccDPOpt/libOpenFOAM.so" #5 Foam::GAMGSolver::Vcycle(Foam::PtrList<Foam::lduMa trix::smoother> const&, Foam::Field<double>&, Foam::Field<double> const&, Foam::Field<double>&, Foam::Field<double>&, Foam::Field<double>&, Foam::PtrList<Foam::Field<double> >&, Foam::PtrList<Foam::Field<double> >&, unsigned char) const in "/opt/openfoam170/lib/linuxGccDPOpt/libOpenFOAM.so" #6 Foam::GAMGSolver::solve(Foam::Field<double>&, Foam::Field<double> const&, unsigned char) const in "/opt/openfoam170/lib/linuxGccDPOpt/libOpenFOAM.so" #7 Foam::fvMatrix<double>::solve(Foam::dictionary const&) in "/opt/openfoam170/lib/linuxGccDPOpt/libfiniteVolume.so" #8 in "/opt/openfoam170/applications/bin/linuxGccDPOpt/simpleFoam" #9 __libc_start_main in "/lib/tls/i686/cmov/libc.so.6" #10 in "/opt/openfoam170/applications/bin/linuxGccDPOpt/simpleFoam" __________________________________________________ _________________ |
