The Symmetry folder supports the following objects:
Symmetry Region: This option is supported for Static and Transient Structural analyses and Thermal/Thermal-Electric analyses.
Linear Periodic: When inserted, this option displays in the tree as a Symmetry Region object only when the Type property is set to . As needed, this property can be modified. It is supported for Static Structural analyses and Thermal/Thermal-Electric analyses.
Periodic Region: This option is supported for Magnetostatic analyses.
Cyclic Region: This option is supported for Harmonic Response (Full), Modal, Static Structural, Thermal, Harmonic Acoustics, Modal Acoustics, Static Acoustics, and LS-DYNA analyses.
Pre-Meshed Cyclic Region: This option is supported for Harmonic Response (Full), Modal, Static Structural, Harmonic Acoustics, Modal Acoustics, and Static Acoustics analyses.
General Axisymmetric: This option is supported for 3D Static Structural analyses only.
Note: Periodic and Cyclic regions:
Support 3D analyses only.
Ensure that a mesh is cyclic and suitable for fluids analyses (the mesh is then matched).
For models generated originally as symmetry models, you may create a Symmetry folder and manually identify Symmetry Region objects or Periodic/Cyclic Region objects. (See Symmetry Workflow in Mechanical.)
