![]() The sliding interface coinciding with the rotating region boundary must be within a fluid volume. ![]() During the calculation, zones linked through the sliding interface remain in contact with each other (i.e., the rotor cells slide relative to stator cells along the interface boundary in discrete steps as shown below). In the Sliding Mesh method, rotor and stator cell zones are connected through a sliding interface. The drawback is that this method is more computationally intensive. The beauty of the Sliding Mesh method is that the mesh within the rotating region is updated throughout the calculation to conform to the position of the rotating component. While this method can be used for various flow configurations, it is especially suitable to provide solutions in cases where the rotor-stator interaction is strong and in cases where the flow exits the rotating component radially. The Sliding Mesh assumes an unsteady flow field and is therefore available for transient solutions only. In 2015, a new rotating region option was added to SOLIDWORKS Flow Simulation : Sliding Mesh.
