Hello guys,

I am trying to solve the very trivial lid-driven cavity flow case with water but I face some problems. The flow is turbulent with cavity dimensions 1 x 1 x 1 (m) and lid speed 0.010048 (fixed to Re=10000).
Although I had changed every reference to epsilon (files taken from the tutorial) with omega. I can't run the case.
Could you propose me anything?
I have put omega (as replica of epsilon substituting every "epsilon" with omega) within the ./0/
also in ./system/ I have changed fvSchemes with the same way.
in ./constant I had writter RANSkOmega (although I am kind of sure that it should be something else, but I didn't find any other reference on the net)
I miss some important factors but I don't know which

Any kind of help is highly appreciated!!!
Thanx in advance,

You need two define
simulationType     RASModel;
in ./constant/turbulenceProperties and
RASModel            kOmegaSST;
turbulence           on;
in ./constant/RASProperties. Then it should work.
