    Dynamic Analysis: Zero stress and displacement results

    Brian Cullen

      Has anyone ever seen results like this: Max Stress: 1.$, 0.0 stress in legend, Max: 0.00 displacement? Trying to get results for a random vibration input.


      Some facts:

      • Split lines representing fastener contact areas (fixed at these surfaces)
      • Random vib up to .3 G^2/Hz between about 600-800 Hz
      • Pinned connections on inner cover
      • Tried both “Allow Penetration” on Inner
        Cover-Housing and “Global Bonded” contact

      Any suggestions as to what is wrong?
