Topic: Additional information from eigenvalue solver
As I mentioned in my previous post, I am building topology optimization simulations with PlaneStress2d and LSpace. One of the optimization criteria is maximizing the first eigenfrequency, so I have some questions specific to EigenValueDynamic.
1) What scaling factor is used to normalize the eigenvectors (ex. L2 norm, mass norm)?
2) What information, if any, besides the eigenfrequency and corresponding eigenvector does the analysis produce? The optimization sensitivities require calculating relative elastic and inertial energy, so ideally I would like to be able to calculate stress/strain with the eigenvector effectively acting as a static displacement without having to formulate the stiffness and mass matrices myself post-simulation.
