Vibration analysis of a structure with cyclic symmetry

  1. Dec 6, 2011 #1
    Lets us say we are doing a vibration analysis of a structure with cyclic symmetry

    In very brief (as pointed out by AlephZero in one of his excellent reply) the whole motion can be represented by complex numbers which describe the motion of one segment.

    Now, my question is:

    1)Is it that,whilst doing the FE analysis we have just one segment (example 1 blade only- considering a turbine wheel) going into the solver - i.e. nodes/eleemnts of just 1 blade?

    2)But the output comprises of all segments- i.e. all the sectors / blades?

    Please help me with this fundamental question!

    Sorry for being too basic
