Applying Planar Symmetry Restraints

You can apply a planar symmetry restraint to force symmetry about a selected face, edge, or point.

A planar symmetry restraint defines boundary conditions that fix certain degrees of freedom for the mesh nodes in the selected geometry. For example, you can define symmetry about a plane X=constant, which will fix the following degrees of freedom:

  • X displacement = 0
  • rotation about the Y-axis = 0
  • rotation about the Z-axis = 0

Support Selection
  1. From the Restraints section of the action bar, click Planar Symmetry .
  2. Optional: Enter a descriptive Name.
  3. Select the geometry support in the model.

    You can apply a planar symmetry restraint to a planar face, a shell edge, or a point on a beam. If you select a face, it is the plane about which symmetry is imposed.

  4. Optional: Select a separate plane of symmetry, if desired. This option is useful if the selected geometry support is an edge on a shell or a point on a beam part.
  5. Click OK.
