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

The exact time step and number of iteration seems to depend on the computer, the numbers of CPUs used, ...!?!


It happens with OpenFOAM 6 and -dev, but not using OpenFOAM-5.x


I reported it at the OpenFOAM bug tracker: https://bugs.openfoam.org/view.php?id=3173


But perhaps, somebody else has seen this before? google doesn't find anything related to the stack trace.


Any ideas?

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