Hi,
I have a problem when i add a nonlinear term(quadratic term) inside my source term and openfoam gets error. what is the best config for fvsolution and fvschemes for these nonlinear effects? diagonal: Solving for rho, Initial residual = 0, Final residual = 0, No Iterations 0 DILUPBiCG: Solving for Ux, Initial residual = 1, Final residual = 1.10082e-06, No Iterations 1 DILUPBiCG: Solving for Uy, Initial residual = 1, Final residual = 1.23009e-06, No Iterations 1 DILUPBiCG: Solving for c, Initial residual = 1, Final residual = 2.55268e-06, No Iterations 1 min(c) = 0 DILUPBiCG: Solving for sigma, Initial residual = 1, Final residual = 1.84628e-06, No Iterations 3 max(sigma) = 1 DILUPBiCG: Solving for hu, Initial residual = 1.61405e-05, Final residual = 5.77265e-11, No Iterations 1 DILUPBiCG: Solving for h, Initial residual = 0.999974, Final residual = 2.25102e-06, No Iterations 1 DICPCG: Solving for p, Initial residual = 1, Final residual = 9.19628e-07, No Iterations 32 diagonal: Solving for rho, Initial residual = 0, Final residual = 0, No Iterations 0 time step continuity errors : sum local = 6.16706e-14, global = -5.94702e-15, cumulative = -5.94702e-15 DILUPBiCG: Solving for k, Initial residual = 1, Final residual = 1.28008e-06, No Iterations 1 diagonal: Solving for rho, Initial residual = 0, Final residual = 0, No Iterations 0 DILUPBiCG: Solving for Ux, Initial residual = 0.196429, Final residual = 1.12715e-07, No Iterations 1 DILUPBiCG: Solving for Uy, Initial residual = 0.111858, Final residual = 3.43147e-08, No Iterations 1 DILUPBiCG: Solving for c, Initial residual = 0.283645, Final residual = 4.53729e-07, No Iterations 1 min(c) = 0 #0 Foam::error:rintStack(Foam::Ostream&) in "/home/farshad/OpenFOAM/OpenFOAM-1.7.1/lib/linux64GccDPOpt/libOpenFOAM.so" #1 Foam::sigFpe::sigFpeHandler(int) in "/home/farshad/OpenFOAM/OpenFOAM-1.7.1/lib/linux64GccDPOpt/libOpenFOAM.so" #2 in "/lib64/libc.so.6" #3 Foam::divide(Foam::Field<double>&, Foam::UList<double> const&, Foam::UList<double> const&) in "/home/farshad/OpenFOAM/OpenFOAM-1.7.1/lib/linux64GccDPOpt/libOpenFOAM.so" #4 Foam::tmp<Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh> > Foam:perator/<Foam::fvPatchField, Foam::volMesh>(Foam::tmp<Foam::GeometricField<doub le, Foam::fvPatchField, Foam::volMesh> > const&, Foam::tmp<Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh> > const&) in "/home/farshad/OpenFOAM/OpenFOAM-1.7.1/applications/bin/linux64GccDPOpt/fsd1" #5 in "/home/farshad/OpenFOAM/OpenFOAM-1.7.1/applications/bin/linux64GccDPOpt/fsd1" #6 __libc_start_main in "/lib64/libc.so.6" #7 at /usr/src/packages/BUILD/glibc-2.11.3/csu/../sysdeps/x86_64/elf/start.S:116 Floating point exception farshad@linux-0dde:~/OpenFOAM/farshad-1.7.1/run/flamesurfacedensity1> Kind Regards, Farshad |
