At first, you are view the results from modal analysis.
So all values are non dimensional.
Actually, for more understanding, you should read "Dynamics of Structure" books.
You should read exactly about how to normalize the eigen vector.
Matrix of eigen vector is normalized follow matrix of mass. So result by MassX (mass) multiply XCM (eigen vector) is a constant.
You can check two results below.
Yesterday is history, tomorrow is a Mystery, and today is a gift that is why it called the present.
