## 28 Oct 2010 Hello, i´m a new OpenFOAM user. Could somebody give me a advice, how I can calculate k (turbulent kinematic energy) and epsilon

SST (Menter's Shear Stress Transport) turbulence model is a widely used and robust two-equation eddy-viscosity turbulence model used in Computational Fluid Dynamics. The model combines the k-omega turbulence model and K- epsilon 'CFD Online Wilcox k-omega turbulence model description'.
