Dear Foamers,
I was using pimpleDyMFoam to simulate some dynamic mesh case. My case can run in serial but not in parallel. Code:
Time = 0.0001 Inverting RBF motion matrix volume continuity errors : volume = 63.99998804, max error = 0, sum local = 0, global = 0 smoothSolver: Solving for Ux, Initial residual = 0.9999999697, Final residual = 1.940639766e-06, No Iterations 1 DICPCG: Solving for p, Initial residual = 1, Final residual = 0.009113619622, No Iterations 10 DICPCG: Solving for p, Initial residual = 0.1448696186, Final residual = 0.001360322043, No Iterations 12 DICPCG: Solving for p, Initial residual = 0.03288304611, Final residual = 0.0003125233115, No Iterations 29 time step continuity errors : sum local = 1.062426731e-09, global = -8.417019943e-11, cumulative = -8.417019943e-11 Moving mesh time step continuity errors : sum local = 1.062426731e-09, global = -8.417019943e-11, cumulative = -1.683403989e-10 DICPCG: Solving for p, Initial residual = 0.01141814687, Final residual = 0.0001126015515, No Iterations 40 DICPCG: Solving for p, Initial residual = 0.004746542347, Final residual = 4.588051877e-05, No Iterations 92 DICPCG: Solving for p, Initial residual = 0.004053370021, Final residual = 0.0003471630065, No Iterations 2 time step continuity errors : sum local = 1.223790396e-09, global = 1.079705363e-12, cumulative = -1.672606935e-10 Moving mesh time step continuity errors : sum local = 1.223790396e-09, global = 1.079705363e-12, cumulative = -1.661809881e-10 smoothSolver: Solving for Ux, Initial residual = 6.683720577e-05, Final residual = 4.632345119e-10, No Iterations 1 DICPCG: Solving for p, Initial residual = 0.001679268542, Final residual = 1.645379057e-05, No Iterations 51 DICPCG: Solving for p, Initial residual = 0.001234871242, Final residual = 1.192388694e-05, No Iterations 11 DICPCG: Solving for p, Initial residual = 0.0003613903132, Final residual = 3.483720583e-06, No Iterations 59 time step continuity errors : sum local = 1.236435531e-11, global = -2.547561024e-12, cumulative = -1.687285492e-10 Moving mesh time step continuity errors : sum local = 1.236435531e-11, global = -2.547561024e-12, cumulative = -1.712761102e-10 DICPCG: Solving for p, Initial residual = 0.000356150859, Final residual = 3.559849006e-06, No Iterations 62 DICPCG: Solving for p, Initial residual = 0.0004029486792, Final residual = 3.729478687e-06, No Iterations 12 DICPCG: Solving for p, Initial residual = 0.0001090817749, Final residual = 7.626294024e-06, No Iterations 2 time step continuity errors : sum local = 2.706125338e-11, global = 2.824445213e-12, cumulative = -1.68451665e-10 Moving mesh time step continuity errors : sum local = 2.706125338e-11, global = 2.824445213e-12, cumulative = -1.656272198e-10 ExecutionTime = 16.72 s ClockTime = 17 s Courant Number mean: 5.566444905e-07 max: 0.0001664760881 velocity magnitude: 0.01569961157 forces output: forces(pressure, viscous)((0 0 0) (0 0 0)) moment(pressure, viscous)((0 0 0) (0 0 0)) forceCoeffs output: Cd = 0 Cl = 0 Cm = 0 Time = 0.0002 [0] [0] [0] --> FOAM FATAL ERROR: [0] face 3013 area does not match neighbour by 0.12569% -- possible face ordering problem. patch: procBoundary0to1 my area: 1.24799e-06 neighbour area: 1.24642e-06 matching tolerance: 0.0001 Mesh face: 551216 vertices: 3((0.00971941 -0.0168322 -0.0854581) (0.00981709 -0.0153605 -0.0854373) (0.00850303 -0.0162224 -0.0843145)) Rerun with processor debug flag set for more information.
