The Antisymmetry node adds an edge or boundary condition that defines an antisymmetry edge or boundary.
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.
If another coordinate system than the Local edge system is used, select a
Symmetry plane normal —
First axis,
Second axis, or
Third axis. This indicates which axis in the selected coordinate system that acts as normal to the antisymmetry plane.
