Stubborn epsilonm residual

Hello,
I am running RANS simulations using twoPhaseEulerFoam. While all other residuals decrease with time, that is not the case for epsilonm, which tends to stay constant. This is typical: I noticed that the fluidisedBed tutorial exhibits the same behavior. Is this expected then? Any clues as to why this is happening would be appreciated.

Hello Albert,
did you find a solution for your problem? I see exactly the same behavior. It can also be reproduced by changing the water velocity to something > 0 in the twoPhaseEulerFoam bubbleColumn tutorial. Thank you Joachim |

I filed a bug at the "official" bug tracker of OpenFAOM: http://www.openfoam.org/mantisbt/view.php?id=1916
It looks like it's also not clear to them what causes this problem. |

Greetings to all!
I haven't checked the values and calculations, but here's what I know on this topic:
Best regards, Bruno

FYI: I was curious and took a look into this. See comment #5684: http://www.openfoam.org/mantisbt/view.php?id=1916#c5684
