I'm modeling two-phase mixture, I got error message of:
turbulent viscosity limited to viscosity ratio of 1.000000e+005 in 226857 cells.... Can I get help to solve it? Thanks |

that is mainly because of the turbulence model you use.
set the appropriate model, and also better approximation of the turbulence parameters in inlet/outlet boundary conditions. |

Hello
I have been also trying to model the flow over rib roughened passages using a realisable k epsilon model. I am modelling the flow using periodic boundary conditions as i am modelling a flow which is already fully developed. what should i do in order to specify my inlet turbulent parameters carefully? I have used intensity and hydraulic diameter of the duct. any body's help is highly appreciated. |

I got this problem too However, my convergence seems to be fine Only the turbulent viscosity is the problem I faced If velocity is not my interest of research, could I just leave it without further fix? Cause I only care about temperature field Hopefully you can help me a little Thanks |
