hi everyone,
when i calculate a case,there are some errors: Create mesh for time = 0 Reading field p Reading field U Reading/calculating face flux field phi Selecting incompressible transport model Newtonian Selecting turbulence model kEpsilon #0 Foam::error::printStack(Foam:http://www.cfd-online.com/OpenFOAM_D...part/proud.gifstream&) #1 Foam::sigFpe::sigFpeHandler(int) #2 Uninterpreted: [0xb7f7f420] #3 Foam::turbulenceModels::kEpsilon::kEpsilon(Foam::G eometricField<foam::vector<dou ble>, Foam::fvPatchField, Foam::volMesh> const&, Foam::GeometricField<double,> const&, Foam::transportModel&) #4 Foam::turbulenceModel::adddictionaryConstructorToT able<foam::turbulencemodels::k epsilon>::New(Foam::GeometricField<foam::vector<do uble>, Foam::fvPatchField, Foam::volMesh> const&, Foam::GeometricField<double,> const&, Foam::transportModel&) #5 Foam::turbulenceModel::New(Foam::GeometricField<fo am::vector<double>, Foam::fvPatchField, Foam::volMesh> const&, Foam::GeometricField<double,> const&, Foam::transportModel&) #6 main #7 __libc_start_main #8 __gxx_personality_v0 at /usr/src/packages/BUILD/glibc-2.3/csu/../sysdeps/i386/elf/start.S:122 what is wrong?thank! |
Hi,
You might have initialize
Hi,
You might have initialized both k and epsilon with zero somewhere. Cheers, Mahdi |

hi,
i have fix the problem,but there is another one.when i when i calculate a case,and show: Create mesh for time = 0 Reading field p Reading field U Reading/calculating face flux field phi Create mesh for time = 0 Reading field p Reading field U Reading/calculating face flux field phi Selecting incompressible transport model Newtonian Selecting turbulence model kEpsilon Starting time loop Time = 0.005 Courant Number mean: 0 max: 0.0777778 DILUPBiCG: Solving for Ux, Initial residual = 1, Final residual = 1.21994e-12, No Iterations 1 DILUPBiCG: Solving for Uy, Initial residual = 1, Final residual = 1.11438e-12, No Iterations 1 DILUPBiCG: Solving for Uz, Initial residual = 1, Final residual = 1.03725e-12, No Iterations 1 DICPCG: Solving for p, Initial residual = 1, Final residual = 9.37245e-07, No Iterations 181 time step continuity errors : sum local = 8.8762e-13, global = -5.54212e-14, cumulative = -5.54212e-14 DICPCG: Solving for p, Initial residual = 4.97522e-08, Final residual = 4.97522e-08, No Iterations 0 time step continuity errors : sum local = 1.3379e-11, global = -4.27122e-12, cumulative = -4.32665e-12 #0 Foam::error::printStack(Foam:http://www.cfd-online.com/OpenFOAM_D...part/proud.gifstream&) #1 Foam::sigFpe::sigFpeHandler(int) #2 Uninterpreted: [0xb7faa420] #3 Foam::divide(Foam::Field<double>&, Foam::UList<double> const&, Foam::UList<double> const&) #4 void Foam::divide<foam::fvpatchfield,>(Foam::GeometricF ield<double,>&, Foam::GeometricField<double,> const&, Foam::GeometricField<double,> const&) #5 Foam::tmp<foam::geometricfield<double,> > Foam::operator/<foam::fvpatchfield,>(Foam::tmp<foam::geometricfie ld<double,> > const&, Foam::GeometricField<double,> const&) #6 Foam::turbulenceModels::kEpsilon::correct() #7 main #8 __libc_start_main #9 __gxx_personality_v0 at /usr/src/packages/BUILD/glibc-2.3/csu/../sysdeps/i386/elf/start.S:122 would someone know that? |
Hi
You are still dividing b
Hi
You are still dividing by zero in your turbulence model. Check that no k or epsilon is initialized to 0. - Niels |
Hi
I'm facing to these errors after modifying my mesh(which are generated in another software). Im working with K omega and I've checked that for zero K or omega but they are ok.Moreover, they work for other meshes. I would appreciate if you have any suggestion. ---------------------------------------------------------------- Create mesh for time = 0 Reading field p Reading field U Reading/calculating face flux field phi #0 Foam::error::printStack(Foam::Ostream&) in "/opt/openfoam211/platforms/linux64GccDPOpt/lib/libOpenFOAM.so" #1 Foam::sigFpe::sigHandler(int) in "/opt/openfoam211/platforms/linux64GccDPOpt/lib/libOpenFOAM.so" #2 in "/lib/x86_64-linux-gnu/libc.so.6" #3 Foam::surfaceInterpolation::makeWeights() const in "/opt/openfoam211/platforms/linux64GccDPOpt/lib/libfiniteVolume.so" #4 Foam::surfaceInterpolation::weights() const in "/opt/openfoam211/platforms/linux64GccDPOpt/lib/libfiniteVolume.so" #5 in "/opt/openfoam211/platforms/linux64GccDPOpt/bin/simpleFoam" #6 __libc_start_main in "/lib/x86_64-linux-gnu/libc.so.6" #7 in "/opt/openfoam211/platforms/linux64GccDPOpt/bin/simpleFoam" Floating point exception (core dumped) ------------------------------------------------------------------- |
