Hi:

I am a new user. I've being testing channel les lately. My case is similar to channel395 in channelOodles folder. I used perturbUDict to initialize velocity field. The problem is after several thousands steps, the results are still converging. Is there other way I can accelerate this? In FLUENT, I know to accerate the convergence, k-epsilon model can be solved first then the solution for velocity field can be used as initial condition for les. Can I do the same thing in OpenFOAM?

I am alos wondering what kind of initial perturbation conditions are applied to channel395? It seems that every variable has an initial field except nuTilda.

Thank you.
