Issues with VoF model with interDyMFoam
Good Morning everybody,
I have been working on a VoF model with interDyMFoam for a while. It is basicly a mixer with fluid injection from below and an outlet at the side. At the top a gas flow from a gas inlet to an outlet is set. The mixer rotates at 500 rpm. The BCs are inlet vel at liquid inlet, outlet vel at gas outlet (I know thats not ideal), pressure at gas inlet. http://s22.postimg.org/w307m6j01/meep.png I can get this model running, but after some time (ca 0.005 - 0.1 s) it crashes. The velocities start to increase at one random single point without clear indication. I observed that the p equations iterate to eternity just before it happens. What I have tried so far:
Does anybody have an idea what else I could try to solve this issue :confused: Thanks for any help. Cheers Mat P.S.: I forgot to mention. for the inlets/outlets with fixed velocity I used fixedFluxPressure BC |
