After doing the "Eigenfrequency Analysis of a Free Cylinder" (Application ID: 271), it is straightforward to visualize the eigenfrequencies of the object (under Results>Mode Shape, 3D) but I would like to be able to extract the Eigenvectors for every position on the object´s surface. How can this be done? I expect some kind of datasheet with 4 columns with on every row the coordinates (x, y, z) of a point on the object, and the eigenvector value in the 4th.

On top of that, I guess there must be a way to extract the stiffness matrix K and mass matrix M, as well as the resulting damping matrix C = μM + λK. Again, how?

Cheers
