Symmetry Constraints
Use Home > Constraints > Symmetry in the Structure or Thermal module of native mode to create a cyclic or mirror symmetry constraint. This command is not available in FEM mode. When you select this command, the Symmetry Constraint dialog box opens with the below items:
Name—The name of the constraint. The color swatch adjacent to Name allows you to change the color of the icon, the distribution, and the text displayed for the constraint.
Member of Set—The name of the constraint set (in Structure) or boundary condition set (in Thermal). You can select an existing set from the drop-down list, or create a new set by clicking New to display the Constraint Sets dialog box.
Type—Select one of the following constraint types. The dialog box changes depending upon your selection:
Mirror (Structure only)
References—For mirror constraints, you can select points, vertices, curves, edges, or surfaces to define the plane of symmetry.
For cyclic constraints, you must make the following selections:
First Side—Define the first side of the cut section.
Second Side—Define the second side of the cut section.
Axis—Select the axis of symmetry. Axis is inactive if the software automatically determines the axis of symmetry.
A constraint set can include cyclic and mirror symmetry constraints, with these limitations:
The constraint set can include only one cyclic symmetry constraint.
The plane defining a mirror symmetry constraint must be orthogonal to the symmetry axis for a cyclic symmetry constraint.
You cannot use the same geometrical entity as a reference for a cyclic symmetry constraint and any other constraint.
