This tutorial outlines the steps needed to set up and run a rotating radial fan analysis. It uses the Moving Reference Frame model, a steady-state approach involving two or more frames of reference that can be stationary or moving relative to each other. The problem geometry is shown in the introductory Rotating System Tutorials section. In this case, two reference frames are used for the analysis - a spinning one representing the fan and blades and a stationary one representing the fan body and inlet section.
