This is my gemoetry, I am setting all boundaries as walls except the liquid level whitch is defined as symmetryPlane. For 0:
p_rgh: fixedFluxPressure ($internaField) U: fixedValue ($internalField) T: fixedValue ($internalField) alpha: zerogradient |

Ok. I'm sorry I'm out of easy ideas since I'm not very expert about MRF and stirred vessels. Hope someone could help more!

hello guys, I have also asked this question on reddit and openfoam google group
I kinda have a same issue as the OP so I post here too. I'm following this tutorial for compressible fluid. except my geometry is little bit different: But when I try to solve it with sonicFoam I get the error below: Code:
Time = 0.002 Courant Number mean: 62.7429 max: 120 diagonal: Solving for rho, Initial residual = 0, Final residual = 0, No Iterations 0 PIMPLE: iteration 1 smoothSolver: Solving for Ux, Initial residual = 0.738285, Final residual = 0.357953, No Iterations 1000 smoothSolver: Solving for Uy, Initial residual = 0.0131426, Final residual = 4.93472e-018, No Iterations 1 smoothSolver: Solving for e, Initial residual = 1, Final residual = nan, No Iterations 1000 smoothSolver: Solving for p, Initial residual = nan, Final residual = nan, No Iterations 1000 diagonal: Solving for rho, Initial residual = 0, Final residual = 0, No Iterations 0 time step continuity errors : sum local = nan, global = nan, cumulative = nan PIMPLE: iteration 2 smoothSolver: Solving for Ux, Initial residual = nan, Final residual = nan, No Iterations 1000 smoothSolver: Solving for Uy, Initial residual = nan, Final residual = nan, No Iterations 1000 smoothSolver: Solving for e, Initial residual = nan, Final residual = nan, No Iterations 1000 --> FOAM FATAL IO ERROR: wrong token type - expected Scalar, found on line 0 the word 'nan' file: C:/Users/.../20180124/system/data.solverPerformance.e at line 0.

What I did not get at the beginning is that both of you are using a Windows version of OpenFOAM. Did you try on Linux? Or maybe use a docker image. |

I solved the issue and you may see more info here in the OpenFOAM google group. There was actually nothing wrong with my code/model. it was just the model not converging due to the a very high input velocity. At least this was my issue. I'm not sure about the OP though!
