Hello everyone,

I am performing a modal analysis and I am wondering if it is valid to use contacts between the components in my model or is it only with static analysis that contacts can be used?

Thank you in advance for any answer!

    Theoretically, Contacts, basically a nonlinear entity will be ignored during a linear modal analysis. 

     

    You may have to hence fix the contacts / replace that area with spring elements.
