I run across a strange bug in buoyantPimpleFoam. If using nOuterCorrectors, at some point of time (and iteration), it crashes at the beginning of a new iteration:
Code:
PIMPLE: Iteration 7 DILUPBiCGStab: Solving for Ux, Initial residual = 0.0026433, Final residual = 6.27222e-06, No Iterations 1 DILUPBiCGStab: Solving for Uy, Initial residual = 0.00255987, Final residual = 6.41521e-06, No Iterations 1 DILUPBiCGStab: Solving for Uz, Initial residual = 0.0026433, Final residual = 6.27221e-06, No Iterations 1 DILUPBiCGStab: Solving for h, Initial residual = 0.00181503, Final residual = 8.62371e-06, No Iterations 1 DICPCG: Solving for p_rgh, Initial residual = 0.00737213, Final residual = 5.90448e-05, No Iterations 35 DICPCG: Solving for p_rgh, Initial residual = 5.906e-05, Final residual = 5.01722e-07, No Iterations 10 DICPCG: Solving for p_rgh, Initial residual = 5.03358e-07, Final residual = 4.33555e-09, No Iterations 16 diagonal: Solving for rho, Initial residual = 0, Final residual = 0, No Iterations 0 time step continuity errors : sum local = 2.42194e-07, global = 2.42194e-07, cumulative = 0.000212064 DICPCG: Solving for p_rgh, Initial residual = 0.00283376, Final residual = 2.0804e-05, No Iterations 35 DICPCG: Solving for p_rgh, Initial residual = 2.0808e-05, Final residual = 1.8005e-07, No Iterations 10 DICPCG: Solving for p_rgh, Initial residual = 1.82666e-07, Final residual = 6.11662e-09, No Iterations 14 diagonal: Solving for rho, Initial residual = 0, Final residual = 0, No Iterations 0 time step continuity errors : sum local = 2.4238e-07, global = 2.4238e-07, cumulative = 0.000212306 #0 Foam::error::printStack(Foam::Ostream&) at ??:? #1 Foam::sigFpe::sigHandler(int) at ??:? #2 ? in "/lib64/libc.so.6" #3 Foam::convergenceControl::getInitialResiduals(Foam::fvMesh const&, Foam::word const&, int, Foam::ITstream&, double&, double&) at ??:?

Any ideas? |

The bug was fixed in OpenFOAM-6 and OpenFOAM-dev (see the bug report)
