Antisymmetry

Use the node adds a boundary condition for an antisymmetry boundary. An antisymmetry condition is fixed in the plane and free in the out-of-plane direction.

When applied to an edge the antisymmetry plane is formed by the normal to the boundary and the edge tangent.

Shell Properties

The selection in this section only acts as a filter for the boundary selection. The constraint is applied all through the thickness of the shell.

All other settings for the node are described in the documentation for Antisymmetry in the Solid Mechanics interface.
