Description

Creates a FEM constraint for keeping the nodes in a planar surface in the same plane.

Usage

  1. There are several ways to invoke the command:
    • Press the FEM ConstraintPlaneRotation button.
    • Select the Model → Geometrical analysis features → Plane multi-point constraint option from the menu.
  2. In the 3D view select the object the constraint should be applied to, which can be a face.

Limitations

  1. Plane rotation constraint can only be applied to a single planar face.
  2. When a plane rotation constraint is applied to the same face as a displacement/fixed constraint, the displacement/fixed constraint takes preference.

Notes

  1. The constraint uses the *MPC card in CalculiX. The card is explained in detail at http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node220.html
