Most of the real life problems you would like to tackle include some sort of turbulence. These [https:// www.youtube.com/watch?v=IPExwi2Ar-g videos]

will give you a detailed explanation on steady-state turbulence modeling in OpenFOAM. It is important to understand the difference between models and which one to choose for a given problem. It is also important to know, how to select a specific model and what you have to change in order to run a successful simulation. You will learn about

  • steady-state turbulence modeling
  • Reynolds-Averaged Navier-Stokes equations
  • RAS models
  • case setup
  • boundary and initial conditions
  • postprocessing
