Hello,
I'm trying tu run the OpenFOAM case $FOAM_RUN/tutorials/compressible/rhoPimpleFoam/ras/angledDuct in Helyx-OS However I always get the same error: Courant Number mean: 17440.39376 max: 100962.1543 Time = 3 diagonal: Solving for rho, Initial residual = 0, Final residual = 0, No Iterations 0 smoothSolver: Solving for Ux, Initial residual = 0.8219688794, Final residual = 0.03374783005, No Iterations 1000 smoothSolver: Solving for Uy, Initial residual = 0.9154234759, Final residual = 0.01271857728, No Iterations 1000 smoothSolver: Solving for Uz, Initial residual = 0.867933914, Final residual = 0.0008835231928, No Iterations 1000 smoothSolver: Solving for h, Initial residual = 0.9996656019, Final residual = 0.01280944088, No Iterations 1000 #0 Foam::error: ![]() #1 Foam::sigFpe::sigHandler(int) in "/opt/openfoam222/platforms/linux64GccDPOpt/lib/libOpenFOAM.so" #2 in "/lib/x86_64-linux-gnu/libc.so.6" #3 Foam::hePsiThermo<Foam: ![]() ![]() ![]() #4 Foam::hePsiThermo<Foam: ![]() ![]() ![]() #5 in "/opt/openfoam222/platforms/linux64GccDPOpt/bin/rhoPimpleFoam" #6 __libc_start_main in "/lib/x86_64-linux-gnu/libc.so.6" #7 in "/opt/openfoam222/platforms/linux64GccDPOpt/bin/rhoPimpleFoam" /home/tom/Engys/RHOPIMPLE/solver.run: line 22: 8576 Floating point exception(core dumped) $SOLVER -case $CASE 2>&1 8577 Done | tee $LOG I would like to know how to set the Pre-Processing properly.

Hi,
I get the same error, did you figure out what the problem was??? Is it due to the thermoPhysicalProperties or boundary conditions? |
