## 1. Introduction (cont'd)

Most or all of the model parameters have very direct relationships
to the structure and material properties of the system.

A finite-element model generally has relatively few *free*
parameters whose values need to be adjusted to fit the data. This assumes,
of course, that the parameters are known *a priori* from other
measurements.
