During a Multistage Cyclic Symmetry simulation, you need to specify one or more Stage objects in combination with Cyclic Regions or Pre-Meshed Cyclic Regions and Interstage objects. Once properly defined, this combination of features enables the accurate and efficient simulation of rotationally periodic structures, from gears to turbomachinery assemblies. For a detailed discussion and underlying theory, see Multistage Cyclic Symmetry Analysis Guide.
This object is scoped to body selections (only). These bodies also define the bodies of a Sector for an associated Cyclic Region or a Pre-Meshed Cyclic Region.
