Using Reference Geometry

You can use a selected reference geometry to apply restraints. The reference can be a plane, axis, edge, or face. Using this option you can prescribe restraints on vertices, edges, faces and beam joints.

In an assembly, you can use reference geometry from the assembly or the components (parts and subassemblies) of the assembly.

The number of degrees of freedom that can be restrained depends on the mesh type and the selected reference.

  • Using a Reference Plane

    You can use a plane as a reference to apply restraints. You can prescribe the translations in directions 1 and 2 of the plane as well as in the direction normal to the plane. For shell meshes, you can prescribe rotations in reference to these directions.

  • Using a Reference Axis

    You can use an axis as a reference to apply restraints. You can prescribe the translations in the radial, circumferential, and axial directions. For shells and beams, you can prescribe rotations in reference to these directions.

  • Using a Model Face

    You can use a planar model face as a reference to apply restraints. You can prescribe the translations in directions 1 and 2 of the face as well as in the direction normal to the face. For shell meshes, you can prescribe rotations in reference to these directions.

  • Using a Model Edge

    You can use a straight model edge as a reference to apply restraints. You can prescribe the translation in the direction of the edge. For shell meshes, you can also specify rotation about the edge.
