Description: The Plane Remains Plane plug-in lets you constrain a planar face on a solid body using one or more of the following techniques:

• Create Planar Constraint—using an analytical rigid surface, a constraint is generated that causes the planar face to remain planar throughout an analysis. The plane can rotate and expand, but all nodes on the face will remain in-plane.

• Create Parallel Planar Constraint—in addition to the analytical rigid surface constraint described above, a constraint is generated that forces the planar face to remain parallel to its original configuration.

• Create Beam Element Normal to Plane—a beam element of any length is generated normal to the planar face and attached to the analytical rigid surface reference node through a kinematic coupling. This technique requires that you first create either of the constraints described above.
