Hello, everyone. I am a new OpenFoam user. For training, I use OpenFoam to simulate a 2D Nasa0012 airfoil model. The inlet air speed is 170 m/s. According to User Guide and the on-line documents, I decided to use rhoSimpleFoam with SpalartAllmars model. and the flowfield is assumed to be compressible. I got the following error message at the first iteration.
smoothSolver: Solving for Ux, Initial residual = 1, Final residual = 1.44986e+60, No Iterations 100 smoothSolver: Solving for Uy, Initial residual = 1, Final residual = 3.05799e+54, No Iterations 100 #0 Foam::error: ![]() #1 Foam::sigFpe::sigHandler(int) at ??:? #2 ? in "/lib/x86_64-linux-gnu/libc.so.6" #3 double Foam::sumProd<double>(Foam::UList<double> const&, Foam::UList<double> const&) at ??:? #4 Foam::PBiCGStab::solve(Foam::Field<double>&, Foam::Field<double> const&, unsigned char) const at ??:? #5 Foam::GAMGSolver::solveCoarsestLevel(Foam::Field<d ouble>&, Foam::Field<double> const&) const at ??:? #6 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::Field<double>&, Foam::Field<double>&, Foam::PtrList<Foam::Field<double> >&, Foam::PtrList<Foam::Field<double> >&, unsigned char) const at ??:? #7 Foam::GAMGSolver::solve(Foam::Field<double>&, Foam::Field<double> const&, unsigned char) const at ??:? #8 Foam::fvMatrix<double>::solveSegregated(Foam::dict ionary const&) at ??:? #9 Foam::fvMatrix<double>::solve(Foam::dictionary const&) at ??:? #10 Foam::fvMatrix<double>::solve() at ??:? #11 ? at ??:? #12 __libc_start_main in "/lib/x86_64-linux-gnu/libc.so.6" #13 ? at ??:? Floating point exception (core dumped) I am not sure if it is just caused by mesh quality, or other issues. And there is rare information I could found for this error message. I am not sure my setup is correct because I could not find a example for the rhoSimpleFoam with SpalartAllmaras model. Therefore I attached the files for your reference. Thanks in advance. Sean |
