Scope

Scoping Method

Low Boundary: Appears if Scoping Method is set to Geometry Selection.

High Boundary: Appears if Scoping Method is set to Geometry Selection.

Low Selection: Appears if Scoping Method is set to Named Selection.

Definition

Scope Mode

Type: Not supported for Cyclic Region.

Number of Sectors (Pre-Meshed Cyclic Region only): The entry range is any real number greater than 2.

Coordinate System

Suppressed

Boundary DOF Orientation (Pre-Meshed Cyclic Region only): Options include Chosen by Solver (default) and Manual. The Chosen by Solver option instructs the solver to automatically assign nodal DOFs at the sector boundary and the Manual 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 Program Controlled and this setting uses a value of -0.0001.
