Dear members,
I am trying to model the rectangular bubble column using twoPhaseEulerFoam. The column is filled with water and the air bubbles are injected from the bottom of the tank. Can somebody helping for this case, I am getting the following error message "------------------------------------------------------------------------------- Selecting dragModel for phase a: SchillerNaumann Selecting dragModel for phase b: SchillerNaumann dragPhase is a Selecting viscosityModel Syamlal Selecting conductivityModel HrenyaSinclair Selecting radialModel Gidaspow Selecting granularPressureModel Lun Selecting frictionalStressModel JohnsonJackson Courant Number mean: 0 max: 0 PIMPLE: Operating solver in PISO mode Starting time loop Reading/calculating field UaMean Reading/calculating field UbMean Reading/calculating field alphaMean Reading/calculating field pMean fieldAverage: starting averaging at time 0 Courant Number mean: 0 max: 0 Max Ur Courant Number = 0 Time = 0.002 DILUPBiCG: Solving for alpha, Initial residual = 0, Final residual = 0, No Iterations 0 Dispersed phase volume fraction = 0 Min(alpha) = 0 Max(alpha) = 1 DILUPBiCG: Solving for alpha, Initial residual = 0, Final residual = 0, No Iterations 0 Dispersed phase volume fraction = 0 Min(alpha) = 0 Max(alpha) = 1 #0 Foam::error:  rintStack(Foam::Ostream&) in "/opt/openfoam210/platforms/linux64GccDPOpt/lib/libOpenFOAM.so"#1 Foam::sigFpe::sigHandler(int) in "/opt/openfoam210/platforms/linux64GccDPOpt/lib/libOpenFOAM.so" #2 in "/lib/libc.so.6" #3 Foam::GAMGSolver::scalingFactor(Foam::Field<double >&, Foam::Field<double> const&, Foam::Field<double> const&, Foam::Field<double> const&) const in "/opt/openfoam210/platforms/linux64GccDPOpt/lib/libOpenFOAM.so" #4 Foam::GAMGSolver::scalingFactor(Foam::Field<double >&, Foam::lduMatrix const&, Foam::Field<double>&, Foam::FieldField<Foam::Field, double> const&, Foam::UPtrList<Foam::lduInterfaceField const> const&, Foam::Field<double> const&, unsigned char) const in "/opt/openfoam210/platforms/linux64GccDPOpt/lib/libOpenFOAM.so" #5 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::PtrList<Foam::Field<double> >&, Foam::PtrList<Foam::Field<double> >&, unsigned char) const in "/opt/openfoam210/platforms/linux64GccDPOpt/lib/libOpenFOAM.so" #6 Foam::GAMGSolver::solve(Foam::Field<double>&, Foam::Field<double> const&, unsigned char) const in "/opt/openfoam210/platforms/linux64GccDPOpt/lib/libOpenFOAM.so" #7 Foam::fvMatrix<double>::solve(Foam::dictionary const&) in "/opt/openfoam210/platforms/linux64GccDPOpt/lib/libfiniteVolume.so" #8 in "/opt/openfoam210/platforms/linux64GccDPOpt/bin/twoPhaseEulerFoam" #9 __libc_start_main in "/lib/libc.so.6" #10 in "/opt/openfoam210/platforms/linux64GccDPOpt/bin/twoPhaseEulerFoam" Floating point exception -----------------------------------------------------------------------------------------------" |
