Understanding MRF: Rotating Physics on a Stationary Mesh
Read & explore →: Understanding MRF: Rotating Physics on a Stationary MeshIntroduction A rotating machine transfers energy between a rotor and a fluid. To simulate that process, we need a model that accounts for rotation. The Multiple Reference Frame approach, or…
