      Hello, I am trying to do a modal analysis on a part.

      I choose all the default options in the Ansys workbench to do that. but when I solve and looking at the mode shapes. I saw there are two values that are exactly the same. Now I want to know is it okay to have multiple modes having the same frequency value? or I am getting the wrong solution.


      I fixed one side of the part. mesh is the default. material is titanium alloy.

      Mode 1 and Mode 2 have the same frequency but the deformation will be in different directions.
