Hai all, im Hazwan, im new in OpenFoam usage,
i got some problem during im running the solver in MHD.. anybody have involve in this kind of problem?? Courant Number mean: 18740.4 max: 2.49723e+06 smoothSolver: Solving for Ux, Initial residual = 0.670023, Final residual = 9.80478e-06, No Iterations 193 smoothSolver: Solving for Uy, Initial residual = 0.846497, Final residual = 9.9397e-06, No Iterations 70 DICPCG: Solving for p, Initial residual = 0.988061, Final residual = 7.26658e-07, No Iterations 392 time step continuity errors : sum local = 0.0726019, global = -0.00074038, cumulative = -0.000826256 DICPCG: Solving for p, Initial residual = 0.28924, Final residual = 4.96783e-07, No Iterations 391 time step continuity errors : sum local = 0.0742087, global = 0.00076225, cumulative = -6.40061e-05 DICPCG: Solving for p, Initial residual = 0.205221, Final residual = 3.70875e-07, No Iterations 391 time step continuity errors : sum local = 0.0385866, global = 0.000402648, cumulative = 0.000338642 #0 Foam::error:rintStack(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 ? at ??:? #7 ? at ??:? #8 ? at ??:? #9 ? at ??:? #10 __libc_start_main in "/lib/x86_64-linux-gnu/libc.so.6" #11 ? at ??:?

Change your time step to make sure that your Courant number stays below 1.
