Antisymmetry
The Antisymmetry node adds an edge or boundary condition that defines an antisymmetry edge or boundary.
Face Defining the Local Orientations
This setting is used in conjunction with a Local edge system. If antisymmetry is prescribed for an edge which is shared between boundaries, the edge system can be ambiguous. Select the boundary which should define the edge system. The default is Use face with lowest number.
Coordinate System Selection (Edges Only)
Specify the coordinate system to use for specifying a symmetry edge. From the Coordinate system list select from:
Local edge system (the default).
Global coordinate system (the standard global coordinate system).
Antisymmetry (Edges only)
If another coordinate system than the Local edge system is used, select an Axis to use as symmetry plane normal. Select 1, 2, or 3 for the first, second, or third axis, respectively.
