kOmegaSST OF2.1 Help needed!
I am trying to get a case of a flow over an airfoil to work using the turbulence model kOmegaSST. I have a mesh where yPlus is around 30. As it is stated in many papers and books this value shoulb be OK if one wants to use a wall function. I also read that the kOmegaSST in openFoam uses a wall function "by default" and one can not avoid using it (any comments on that?).
My parameters are attached to this thread, I donīt understand what I have done wrong, but when the Re number is 20.000 the case is working, but it will diverge when Re=700.000. Any help on this will be greatly appreciated as I am really lost with all what is written about kOmegaSST, as it seems that there are "many ways" to use it in OpenFoam.
I would like that this exchange space will serve to discuss that issue about kOmegaSST.
