Who can I apply cyclic symmetry boundary conditions to a sector model in Simulation at 11.0. I am using the CYCLIC command in a command snippet, but the results do not look right.


For static cyclic symmetry as you are doing (as opposed to modal cyclic symmetry), it would be more efficient to use just a single sector, cyclic symmetry analysis with the CPCYC command as I show below.

When the CYCLIC command is used, a duplicated sector is created during solution. This is unnecessary and makes postprocessing in Simulation impossible. Modal cyclic symmetry, in which higher modes are obtained through special constraint equations between double sectors, is not supported in Simulation and if done with a command snippet cannot be postprocessed.

! cyclic ! Don't use in Simulation at 11.0
