Hello everyone!
My name is George and I need to simulate a flow in a wind tunnel using the simpleFoam solver, but the simulation has presented the following error: #0 Foam::error: ![]() #1 Foam::sigFpe::sigHandler(int) at ??:? #2 ? in "/lib/x86_64-linux-gnu/libc.so.6" #3 Foam::GaussSeidelSmoother::smooth(Foam::word const&, Foam::Field<double>&, Foam::lduMatrix const&, Foam::Field<double> const&, Foam::FieldField<Foam::Field, double> const&, Foam::UPtrList<Foam::lduInterfaceField const> const&, unsigned char, int) at ??:? #4 Foam::GaussSeidelSmoother::smooth(Foam::Field<doub le>&, Foam::Field<double> const&, unsigned char, int) const at ??:? #5 Foam::smoothSolver::solve(Foam::Field<double>&, Foam::Field<double> const&, unsigned char) const at ??:? #6 ? in "/opt/openfoam5/platforms/linux64GccDPInt32Opt/bin/simpleFoam" #7 ? in "/opt/openfoam5/platforms/linux64GccDPInt32Opt/bin/simpleFoam" #8 ? in "/opt/openfoam5/platforms/linux64GccDPInt32Opt/bin/simpleFoam" #9 ? in "/opt/openfoam5/platforms/linux64GccDPInt32Opt/bin/simpleFoam" #10 __libc_start_main in "/lib/x86_64-linux-gnu/libc.so.6" #11 ? in "/opt/openfoam5/platforms/linux64GccDPInt32Opt/bin/simpleFoam" I have no idea how to debug this!!! The flow is laminar, incompressible and the velocity is 13 m/s in the inlet. I do have to finish this for my graduate conclusion!! Please, if anyone could help me will be very grateful!! Thank you! |

Tip: When posting the contents of your fvSolutionDict use the [*code][/code*] tags. Without the *. That keeps your post tidy.

Hi RobertHB!!
Thank you very much for your answer! This is my fvSolution for this case: solvers { p { solver PCG; preconditioner DIC; tolerance 1e-06; relTol 0.05; } pFinal { $p; tolerance 1e-06; relTol 0; } U { solver smoothSolver; smoother symGaussSeidel; tolerance 1e-05; relTol 0; } } SIMPLE { nCorrectors 3; nNonOrthogonalCorrectors 1; pRefCell 0; pRefValue 0; } I've already changed the "smoother" on velocity(U) to "GaussSeidel" but without success, too. If you have any idea, please tell me!! Thanks!! |

Hi George,
Following on from Robert/s suggestion of the U solvers that may be a bit premature. Looking through the first two lines of the stack trace: Code:
#0 Foam::error:printStack(Foam::Ostream&) at ??:? #1 Foam::sigFpe::sigHandler(int) at ??:? What is the quality of your mesh for this solution? Are you running steady or transient? Can you double check your boundary conditions and initial conditions? Cheers, -pete |
