Hello everybody,

I'm quite new to OpenFoam, and i was trying to test the k-omega-SST turbulence model in OF 1.4, and i got some errors. I would like to check back with you guys if I did the right things.

I'm running a 2D case on a "elbow"-tube geometry (like this: _| , hope you understand) with the simpleFoam-solver.

The following errors occurred:

1. The solver needed a "omega" file.
-> I made a copy of the "k" file, replacing the k with omega, changed the dimensions to [0 0 -1 0 0 0 0] and made an initial guess for omega via omega = sqrt(k) / L.

2. I got an error saying "keyword DomegaEff,omega not found in dictionary laplacianSchemes" or something like that.
-> I inserted the line " laplacian(DomegaEff,omega) Gauss linear corrected;" in the "fvSchemes" file

After this, the case was calculated without errors.
Now: Is what i did the right way to do this, and is this from a mathematical/physical view correct??

Strange thing: I wanted to copy-paste the laplacian-error in this thread, so i commented the "laplacian..." line out of fvSchemes, but the solver runs without problems, i cannot reproduce this error...

Keep up the good work!

Peter
