Type: Not supported for Cyclic Region. Number of Sectors (Pre-Meshed Cyclic Region only): The entry range is any real number greater than 2. Boundary DOF Orientation (Pre-Meshed Cyclic Region only): Options include (default) and . The option instructs the solver to automatically assign nodal DOFs at the sector boundary and the option requires you to specify the orientations using Nodal Orientation. See the direct FE example in the Pre-Meshed Cyclic Symmetry section for a discussion on the solver's DOF requirements and how to apply them in Mechanical APDL Solver with Nodal Orientation objects. |
Tolerance - Pre-Meshed Cyclic Region Only. |
Relative Distance Tolerance: The default setting is
and this setting uses a value of
