This tutorial illustrate the procedure for setting up and solving problem using the MRF capability. As an example, the flow field on a 2D section of a centrifugal Blower will be calculated. Although this is a general methodology that can be applied to cases where more than one reference frame is moving, this example will be limited to a single rotating reference frame.

This tutorial demonstrates how to do following.....

1. Create mesh interface.

2. Specify different frames of reference for different fluid zones.

3. Set the relative velocity of each wall.

4. Calculate a solution using the pressure - based Solver.
