Benefitting from Cyclic Symmetry in ANSYS Mechanical and Mechanical APDL
A geometry is called cyclic symmetrical when a structure is rotationally symmetrical about one axis so that the full structure can be produced by copying the cyclic portion. Fan wheels, spur gears, and turbine blades are all examples of structures that exhibit cyclic symmetry. For example, a 36-blade turbine wheel assembly may have 36 repeating 10 degree segments.
ANSYS Mechanical and Mechanical APDL can use cyclic symmetry to more efficiently solve static, modal, harmonic, and buckling analysis. It is only necessary to build and mesh one of the repeating segments, so the efficiency gain can be significant. Mechanical and MAPDL will solve for the behavior of that sector and use that single-sector response to construct the response for the full component.
This webinar will explain how cyclic symmetry models are created and analyzed using ANSYS Mechanical and Mechanical APDL 14.0.
