Hey all, I am trying to solve a simple flat plate film cooling problem. I am attaching the 0, constant and system files.
This is the error I get. Code:
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // Create time Create mesh for time = 0 SIMPLE: Convergence criteria found p: tolerance 0.001 U: tolerance 0.0001 e: tolerance 0.001 "(k|epsilon|omega)": tolerance 0.001 Reading thermophysical properties Selecting thermodynamics package { type heRhoThermo; mixture pureMixture; transport const; thermo hConst; equationOfState perfectGas; specie specie; energy sensibleEnthalpy; } Reading field U Reading/calculating face flux field phi pressureControl pMax 0 pMin 0 Creating turbulence model Selecting turbulence model type RAS Selecting RAS turbulence model kEpsilon RAS { RASModel kEpsilon; turbulence on; printCoeffs on; Cmu 0.09; C1 1.44; C2 1.92; C3 0; sigmak 1; sigmaEps 1.3; } No MRF models present No finite volume options present #0 Foam::error::printStack(Foam::Ostream&) at ??:? #1 Foam::sigFpe::sigHandler(int) at ??:? #2 ? in "/lib/x86_64-linux-gnu/libc.so.6" #3 Foam::divide(Foam::Field<double>&, Foam::UList<double> const&, Foam::UList<double> const&) at ??:? #4 Foam::operator/(Foam::tmp<Foam::Field<double> > const&, Foam::UList<double> const&) at ??:? #5 Foam::CompressibleTurbulenceModel<Foam::fluidThermo>::nu(int) const at ??:? #6 Foam::nutkWallFunctionFvPatchScalarField::nut() const at ??:? #7 Foam::nutWallFunctionFvPatchScalarField::updateCoeffs() at ??:? #8 Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh>::Boundary::evaluate() in "/opt/openfoam7/platforms/linux64GccDPInt32Opt/bin/rhoSimpleFoam" #9 Foam::RASModels::kEpsilon<Foam::EddyDiffusivity<Foam::ThermalDiffusivity<Foam::CompressibleTurbulenceModel<Foam::fluidThermo> > > >::correctNut() at ??:? #10 ? in "/opt/openfoam7/platforms/linux64GccDPInt32Opt/bin/rhoSimpleFoam" #11 __libc_start_main in "/lib/x86_64-linux-gnu/libc.so.6" #12 ? in "/opt/openfoam7/platforms/linux64GccDPInt32Opt/bin/rhoSimpleFoam" Floating point exception (core dumped) In this problem, there is a mainstream flow and a " jet in crossflow". I started to use rhosimplefoam as it is easier to add temperatures to the inlet flows. I have read elsewhere that the above floating point exception error occurs when there is a division by wero for k, but I really cant find the error ( maybe it is in front of my eyes, but I spent enough time finding it before posting here) Will do wonders if someone could help |

Hello, I have already tried the iso thermal case and it runs well using simpleFoam
