Cyclic Symmetry Modal Analysis

omerugursimsek

Hi everyone,

 

I have been performing cyclic symmetric modal analysis using EIGRL card. I would like to have some results belongs to a certain Nodal Diameter.I am an Ansys user as well and it is possible to define harmonic indexes in order to have natural frequencies for various nodal diameters. How does it work in  optistruct? How can  I have natural frequencies at different Nodal diameters.

 

Thank you

There is an alternative approach that you can use to run the harmonic analysis using a cyclic symmetry model. At the each edge of the sector you can apply Periodic Boundary condition.

Please refer to the attached material from help.
