The SOLIDWORKS Flow Simulation team has added powerful new functionality to their arsenal, Rotating Mesh Regions. Rotating mesh regions or “sliding mesh regions” allow the user to rotate geometry in the model and drive the fluid of the system. If you are designing any device that utilizes, impellers, propellers, or other rotational apparatus Flow Simulation can provide results such as flow rate, pressure drop, velocity, and many more, all based on the rotation of the geometry. A transient or time based study is required to use the Rotating Mesh Region.
If you have SOLIDWORKS Flow Simulation 2015 already loaded you can find the rotating mesh region under the rotation type “Local regions(s) (Sliding mesh). Utilize the rotating region boundary condition as usual in the Flow Simulation Design Tree.
