Symmetry
The Symmetry node adds an edge (3D), boundary (2D), or point (2D and 3D) condition that defines asymmetry edge, boundary, or point.
Coordinate System Selection
Specify the coordinate system to use for specifying the orientation of the symmetry plane. See the section Coordinate System Selection for Edge Load.
Symmetry
Select an Axis to use as symmetry plane normal to specify the direction of the normal to the symmetry plane in the selected coordinate system.
For 2D models, select 1 or 2 for the first or second axis, respectively.
For 3D models, select 1, 2, or 3 for the first, second, or third axis, respectively.
