Moving Wall Effect and Zones

Ansys fluent gives us the ability to define conditions for the boundary (wall) as moving. In addition to this we have entire set of capabilities to set up the zone as moving & rotating. We have brought together some important concepts to quickly understand this area and prospective application of this concept in our simulation related problems.
