I am new to MRF simulations. I was wondering how to properly define (the dimensions) rotating zone during the mesh procedure? Let’s suppose I have a propeller and I want to simulate the flow field around it. Is the rotating zone defined as the disc (volume which will be intersected during the rotation) in which the propeller rotates? or it should be a little bit larger than this? if so, by how much.
I tried finding similar question on this forum but I was unable to do so. If there is a similar question in the forum, please tell me. Any help is appreciated.
