    Prestressed CYCLIC Harmonic Analysis in ANSYS

    Hello, I would like to get the amplitudes after the Harmonic Response analysis using a pre-stressed CYCLIC struture. I have done the Static Analysis with Rotational speed using the PSTRES,ON and EMATWRITE,YES. This is CYCLIC analysis. I now need to do the forced response at ND8, I have...

    ANSYS prestress (stifness matrix extraction)

    Thanks! Yes, I was doing the same procedure than you, but I was using CYCLIC command. When I use CYCLIC, ANSYS needs to create another sector for the analysis and this is what I didnt want. So now I am trying to solve for only one sector, but using CPCYC it seems to work. I have to see what...

    ANSYS prestress (stifness matrix extraction)

    Hej Garry, Well, I have actually tried. But in I am not sure if I have tried in the right stage. The procedure for the prestress is the following: 1)With only on sector of the geometry, create a cyclic static prestress analysis 2)Step 1) creates an .EMAT file that it needs for the modal...

    ANSYS prestress (stifness matrix extraction)

    Hello hello, I am working in ANSYS and I only to get the stiffness and mass matrices for further analysis. I have a disk, which a model as only a sector, and I do the static and the cyclic modal analysis. I know that ANSYS when solving for cyclic, doubles the matrices (double sector and basic...
