    Normalized eigenvectors

    Hi, Does anyone know how the eigenvectors are normalized in cyclic symmetry analysis of ANSYS 7.0? By the way, I found the following information in ANSYS website. In modal cyclic symmetry, this becomes even more complicated because of the presence of the duplicate sector. Here the mass...

    Modal Cyclic Symmetry Analysis using ANSYS7.0

    I've conducted cyclic symmetry analysis of a sector model of a bladed disk. (shell63 in cylindrical coord) I wrote Fortran code to take out complex modeshapes. I also obtaned the mass and stiffness matrices using Rdfull.exe. I've been trying to compute the modal mass matrix as the unit matrix...
