I am trying to run the test case i.e. DTMB 5415 to see the wave formation and resistance prediction. I am using OF 2.2.0 version together with the LTSInterfoam. As a template i used the setup already defined in the wigley hull tutorial.
But i am having convergence problem with this test case and following is the attached error for my test case: // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // Create time Create mesh for time = 0 Reading field p_rgh Reading field U Reading/calculating face flux field phi Reading transportProperties Selecting incompressible transport model Newtonian Selecting incompressible transport model Newtonian Selecting turbulence model type RASModel Selecting RAS turbulence model kOmegaSST kOmegaSSTCoeffs { alphaK1 0.85034; alphaK2 1; alphaOmega1 0.5; alphaOmega2 0.85616; gamma1 0.5532; gamma2 0.4403; beta1 0.075; beta2 0.0828; betaStar 0.09; a1 0.31; b1 1; c1 10; F3 false; } Reading g Calculating field g.h No finite volume options present PIMPLE: Operating solver in PISO mode time step continuity errors : sum local = 2.28352e-05, global = 1.18752e-11, cumulative = 1.18752e-11 GAMGPCG: Solving for pcorr, Initial residual = 1, Final residual = 1.32922, No Iterations 1001 time step continuity errors : sum local = 3.0353e-05, global = -4.41479e-08, cumulative = -4.4136e-08 Courant Number mean: 3.31708 max: 180.716 Starting time loop Time = 0.2 Flow time scale min/max = 0.00030183, 0.400348 Smoothed flow time scale min/max = 0.00030183, 0.400348 MULES: Solving for alpha1 Phase-1 volume fraction = 1 Min(alpha1) = -0.156304 Max(alpha1) = 2.04597 smoothSolver: Solving for omega, Initial residual = 0.0829235, Final residual = 7.77335e+152, No Iterations 1000 smoothSolver: Solving for k, Initial residual = 1, Final residual = 1.19018e-152, No Iterations 1 bounding k, min: 1.44309e-162 max: 0.00148983 average: 0.000149309 smoothSolver: Solving for Ux, Initial residual = 1, Final residual = 2802.27, No Iterations 1000 smoothSolver: Solving for Uy, Initial residual = 1, Final residual = 0.356035, No Iterations 1000 smoothSolver: Solving for Uz, Initial residual = 1, Final residual = 0.455123, No Iterations 1000 #0 Foam::error: ![]() #1 Foam::sigFpe::sigHandler(int) at ??:? #2 in "/lib64/libc.so.6" #3 Foam::GAMGSolver::scale(Foam::Field<double>&, Foam::Field<double>&, Foam::lduMatrix const&, Foam::FieldField<Foam::Field, double> const&, Foam::UPtrList<Foam::lduInterfaceField const> const&, Foam::Field<double> const&, unsigned char) const at ??:? #4 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 at ??:? #5 Foam::GAMGSolver::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&) at ??:? #8 at ??:? #9 __libc_start_main in "/lib64/libc.so.6" #10 at /home/abuild/rpmbuild/BUILD/glibc-2.15/csu/../sysdeps/x86_64/elf/start.S:116 Floating point exception Thanks. |
