Symmetry Restraint for Solid Models
For solid models, every face that is coincident with a plane of symmetry should be prevented from moving in its normal direction. The Symmetry restraint type applies this condition automatically to all selected faces.
The following are some examples of models that are symmetric with respect to one or more planes.

This model is symmetrical with respect to one plane. You can analyze one half of the model. Apply the Symmetry restraint type to the faces of symmetry.

|
This model is symmetrical with respect to two planes. You can analyze one quarter of the model. Apply the Symmetry restraint type to the faces of symmetry.

|
This model is axisymmetric. To analyze the model, you can use a wedge. Apply the Symmetry restraint type to the faces of symmetry. Although the angle of the wedge is arbitrary in theory, using a very small angle may produce bad element at the tips.
