Hi... 

currently, I'm working on a modal analysis project and I've performed a frequency analysis on a continuous FE model in abaqus (free-free condition). I want to discretize this model in order to form lumped model. how can I obtain mode shapes vectors for first modes.( for example, a 3*3 mode shape matrix for first three non-rigid modes. it is important for the mode shapes to be normalized for post processing.
