Circular Symmetry
Circular symmetry allows you
to analyze a model with circular patterns around an axis by modeling a
representative segment. The segment can be a part or an assembly . The
geometry, restraints, and loading conditions must be similar for all other
segments making up the model. Turbine, fans, flywheels, and motor rotors
can usually be analyzed using circular symmetry.

The Circular Symmetry restraint
can be applied for a solid model and for a static study only. You define
it for two sections, and you need to define the axis of revolution for
the symmetry.

Selectable entities |
Two sets of faces. Each set represents one side. The faces should be
similar and can be non-planar. The areas of the faces in the two sets
must be similar. |
|
Translations |
The program enforces equal translations at each pair of nodes with similar
relative positions on the two sections. |
Nodes
on opposite sections with similar relative positions displace similarly.
For example, locations with similar color of dots in the figure deform
similarly.
