Hey,
I'm currently a intern in a startup and I have to work on OpenFoam. I'm trying to understand the differencies between all the fvScheme that I can use. I started with the ddt schemes. I read the specificity of each and that Crank-Nicolson 0.9 is the most robust. But when I use this scheme, I got this error message: Courant Number mean: 0.0112231 max: 7.96644 #0 Foam::error: ![]() #1 Foam::sigFpe::sigHandler(int) at ??:? #2 ? in "/lib/x86_64-linux-gnu/libc.so.6" #3 Foam::symGaussSeidelSmoother::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::symGaussSeidelSmoother::smooth(Foam::Field<d ouble>&, 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/openfoam-dev/platforms/linux64GccDPInt32Opt/bin/icoFoam" #7 ? in "/opt/openfoam-dev/platforms/linux64GccDPInt32Opt/bin/icoFoam" #8 ? in "/opt/openfoam-dev/platforms/linux64GccDPInt32Opt/bin/icoFoam" #9 ? in "/opt/openfoam-dev/platforms/linux64GccDPInt32Opt/bin/icoFoam" #10 __libc_start_main in "/lib/x86_64-linux-gnu/libc.so.6" #11 ? in "/opt/openfoam-dev/platforms/linux64GccDPInt32Opt/bin/icoFoam" Exception en point flottant (core dumped) Do someone know why? And do you have good documents that explain very well how to use each scheme? Best regards; Lucie |
