### 6.3 Damped dynamic problem

\[ \mathbf K \mathbf u + \mathbf C \dot {\mathbf u} +
\mathbf M \ddot{\mathbf u} = \mathbf f \]
There are multiple approaches to solving this problem.

#### 6.3.1 Modal analysis

Modal analysis involves representing responses to
arbitrary inputs by weighted superposition of a number of the natural
modes. This is very efficient if a small number of modes can be used
without losing accuracy.
