yes sir, that might be case of double mode. And the report with which I am comparing is of Modal Analysis using ANSYS. In short I have report of modal analysis performed using ANSYS by someone else and I am trying to perform the modal analysis on same modal and get the same outputs. But somehow m y output is not similar to him not even mode shapes. I will post mode shapes as well in a while to give you idea about how my model is behaving.
