How to Define Symmetry Conditions?

Symmetry conditions can be defined if there is no constrained boundary condition (fixed value, un-deformable remote force, or fixed support) applied to the adjacent face.

If a symmetry plane is parallel to the X,Y, or Z axis, a fixed value boundary condition can be used.

In the following example, you see a quarter of a pipe. To assign the symmetry condition in X-axis, displacement of X is assigned as zero. This ensures the model to be constrained in x-axis. Meanwhile, the displacement on the Y and Y axes are set as unconstrained.

To assign the symmetry condition in Y-axis, displacement of Y is assigned as zero. This ensures the model to be constrained in x-axis. Meanwhile, the displacement on the X and Z axes are set as unconstrained.
