There is a documented issue regarding turbulent cases: Different dimensions for dimensions Issue in FSI when turbulence model is used - OpenFOAM adapter · Issue #158 · precice/openfoam-adapter · GitHub

I am trying to reproduce the issue, could you maybe help?

Trying to create a setup to trigger and debug https://github.com/precice/openfoa…m-adapter/issues/158. It currently does not trigger the checkpointing issue (OpenFOAM v2312), but instead diverges (the numerical setup is arbitrary, but it should already trigger the checkpointing issue before): ``` Courant Number mean: 51.1606 max: 4247.53 Time = 0.3 PIMPLE: iteration 1 diagonal: Solving for rho, Initial residual = 0, Final residual = 0, No Iterations 0 DILUPBiCGStab: Solving for Ux, Initial residual = 0.802428, Final residual = 3.49139e-07, No Iterations 36 DILUPBiCGStab: Solving for Uy, Initial residual = 0.779756, Final residual = 7.00548e-08, No Iterations 40 DILUPBiCGStab: Solving for h, Initial residual = 0.868425, Final residual = 7.90218e-07, No Iterations 35 DICPCG: Solving for p_rgh, Initial residual = 0.841614, Final residual = 0.00718705, No Iterations 70 diagonal: Solving for rho, Initial residual = 0, Final residual = 0, No Iterations 0 time step continuity errors : sum local = 4.42713, global = -3.13549, cumulative = -3.14201 DICPCG: Solving for p_rgh, Initial residual = 0.699451, Final residual = 8.56824e-09, No Iterations 186 [stack trace] ============= #1 Foam::sigFpe::sigHandler(int) in /usr/lib/openfoam/openfoam2312/platforms/linux64GccDPInt32Opt/lib/libOpenFOAM.so #2 ? in /lib/x86_64-linux-gnu/libc.so.6 #3 Foam::divide(Foam::Field<double>&, Foam::UList<double> const&, Foam::UList<double> const&) in /usr/lib/openfoam/openfoam2312/platforms/linux64GccDPInt32Opt/lib/libOpenFOAM.so #4 ? in /usr/lib/openfoam/openfoam2312/platforms/linux64GccDPInt32Opt/bin/buoyantPimpleFoam #5 ? in /usr/lib/openfoam/openfoam2312/platforms/linux64GccDPInt32Opt/bin/buoyantPimpleFoam #6 ? in /lib/x86_64-linux-gnu/libc.so.6 #7 __libc_start_main in /lib/x86_64-linux-gnu/libc.so.6 #8 ? in /usr/lib/openfoam/openfoam2312/platforms/linux64GccDPInt32Opt/bin/buoyantPimpleFoam ============= Floating point exception (core dumped) ```
