ModalSolver
===========

The ``ModalSolver`` computes eigenmodes via the generalized eigenvalue problem
for the assembled stiffness and mass matrices. It stores eigenvectors and
values in the global data and terminates.

Overview
--------

Solver type: ``ModalSolver``

- Problem: solves ``K v = \lambda M v``
- Outputs: eigenvectors and eigenvalues
- Termination: deactivates model after solve
