Modal Analysis

      Hello everybody,

      i'm pretty new to Ansys, and i want to make a modal analysis simulation from a robot. When i solve the model as whole i get only zeros for the first 10 Modi. I tried to split the Model and when i solve the first part it works (i still dont know if the result are correct) but the other parts will still give zero as a result. 

      in the last Foto after connecting a new element, the whole model does'n work anymore, giving zero as a result.

      What can be the reason for such a result?

      Thanks in advance!

      Hi 

      Since this is Mechanical I would suggest to post it in the Mechanical forum.

      /forum/forums/forum/discuss-simulation/structures/

      All the best

      Hi,

      Did you apply any boundary conditions to constrain the model?
