CYCLIC SYMMETRY IN HYPERWORKS

Hi, I am a new user of hyperworks and i am currently using the 2017 student edition. I am working on jet engine blades static structural analysis. Considering the cyclic symmetry involved in the problem statement i am trying to stimulate just one blade with the help of cyclic symmetry but i am having a problem setting this up since hyperworks doesn't have any direct GUI option for that. I have been searching for the last week on forum for axi symmetry and cyclic symmetry and all i was able to find was a tutorial of axi symmetry which says that tangential displacement needs to be restricted but according to me that is only possible for certain specific situations of cyclic symmetry problems. I am trying to use PERBC to make the opposite faces of geometry behave same to simulate cyclic symmetry but i am not able to figure out how to implement that. Can anyone help me with that?

    HI,

     

    Cyclic symmetry is under development and should be available in coming version of HyperWorks.

    Hi,

    I think we may use MPC to constraint cyclic symmetry

    Could you describe your model with applied loads and constraints namely?

    HI,

     

    PERBC can be an option to manually add symmetry.

     

    Here is a tutorial OS-E: 0705 Periodic Boundary Conditions.

     

    Our developers are working on CYCSYM to accommodate cyclic symmetric for analysis and optimization
