Hi,
I am new to OF and want to learn how turbulence models are used in it. There are tutorials which use k-epsilon and k-omega-sst models. I want to try other turbulence models like q-zeta model, Spalart-Allmaras model and LES models like Smagorinsky, k-omega-sst-SAS and various other models given in OF. Are there any tutorials using these models? I need them to know the input files required to define constants and other inputs to the model. Thank You Regards, Achinta |

The model constant can be found in the codes of this models

Hi,
I saw some files in $HOME/OpenFOAM/OpenFOAM-1.6/src/turbulenceModels/incompressible/RAS/qZeta I am not able to understand which one should be given as input in 0/ folder (initial conditions). I want to know the syntax of the inputs. Thank You. Regards, Achinta |

by default the modeling constant do not need to be modified
and it is not put in the 0/ directionary |

Hi,
I want to use Lien Cubic K-Epsilon model for incompressible turbulent flow. Which divergence scheme is best for nonlinearStress i.e. div(nonlinearStress)? Thank You. Regards, Achinta |
