Hi everybody,

I am simulating a fish passage and I succeeded in this by using the standard k-eps turbulence model. I have tried tu use the K-eps RNG, but the solution always diverges, also using different interpolation schemes and pressure velocity coupling schemes. Do you know how to stabilize it? My simulation is steady state.

Thank you
Bye
