Hello,
I was wondering if anyone has successfully specified a RAS model for all phases of a 3-phase flow? I have oil/air/water in a pipe, 1) when I set all to kEpsilon I have an immediate crash at the first iteration GAMG: Solving for p_rgh, Initial residual = 0.00296003, Final residual = 1.99966e-05, No Iterations 12 GAMG: Solving for p_rgh, Initial residual = 0.00122383, Final residual = 1.07626e-05, No Iterations 13 GAMGPCG: Solving for p_rgh, Initial residual = 1.92961e-05, Final residual = 8.79505e-08, No Iterations 10 #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::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 Foam::fvMatrix<double>::solveSegregated(Foam::dict ionary const&) at ??:? #7 Foam::fvMatrix<double>::solve(Foam::dictionary const&) in "/opt/openfoam8/platforms/linux64GccDPInt32Opt/bin/multiphaseEulerFoam" #8 Foam::SolverPerformance<double> Foam::solve<double>(Foam::tmp<Foam::fvMatrix<doubl e> > const&) at ??:? #9 Foam::RASModels::kEpsilon<Foam::PhaseCompressibleM omentumTransportModel<Foam::phaseModel> >::correct() at ??:? #10 Foam::phaseSystem::correctTurbulence() at ??:? #11 ? in "/opt/openfoam8/platforms/linux64GccDPInt32Opt/bin/multiphaseEulerFoam" #12 __libc_start_main in "/lib/x86_64-linux-gnu/libc.so.6" #13 ? in "/opt/openfoam8/platforms/linux64GccDPInt32Opt/bin/multiphaseEulerFoam" Floating point exception (core dumped) 2) when I set all to mixtureKEpsilon I have the following error --> FOAM FATAL ERROR: Call from a two-phase model in a multi-phase system. From function const Foam::phaseModel& Foam::phaseSystem::otherPhase(const Foam::phaseModel&) const in file ../phaseSystems/lnInclude/phaseSystemI.H at line 118. 3) When I set all to LaheyKEpsilon I have the following error --> FOAM FATAL ERROR: Call from a two-phase model in a multi-phase system. From function const Foam::phaseModel& Foam::phaseSystem::otherPhase(const Foam::phaseModel&) const in file ../phaseSystems/lnInclude/phaseSystemI.H at line 118. Could advise on the error in (1)... And have (2) and (3) not been implemented for 3-phase and more? Jason |
