Modal analysis – frequency values repeated

  Hi, I am running a modal analysis (ANSYS AIM) using hollow bodies (manually inserted thickness) and the frequency results are the ones in the pic attached. But when I run the same sim using solid bodies, the frequency values change and mode shapes as well. Can anyone explain why this is happening? What's the source of this issue?

  Hello SJ ,
  
  I tried recreating the issue on my end with a simpler model, and I got results similar. I will investigate this further and will get back to you with more information as soon as possible.
  
  Regards.
