A brief introduction to Multiple Reference Frame (MRF) approach, which is used to simulate the motion of rotors/impellers and blades. The following topics are covered:
1) 10:56 What additional source terms are added in the Single Reference Frame (SRF) approach?
3) 17:34 What additional source terms are added in the Multiple Reference Frame (MRF) approach?
4) 19:22 How is the face volume flux modified in the MRF approach?
Frozen Rotor and Mixing Plane approaches will be considered in a separate video.
