====== Modal Solver ======
<WRAP group>
<WRAP half column>
A modal solver determines the effects of vibration on a geometry, and determines the frequencies at which the component will naturally resonate.

A modal solver has the following inputs:
  * SS: a [[wiki:sns:intactgh:solver_settings|solver settings block]]
  * C: the components to perform the simulation on (from a [[components|component block]])
  * R: restraints (from a [[restraints|restraint block]]). If no restraint is specified, the solver will compute modes and frequencies for **Free-Free vibration**.
  * F: the number of frequencies to calculate
  * SM: solver mode boolean, by default false requires manually pressing "solve" and true automatically solves after changing any input upstream.
