Measures for Dynamic Analyses

For dynamic analyses, you want to study the model's behavior over time, at a point in time, or as a function of frequency. User-defined measures are the only measures that apply to dynamic random analyses.

With dynamic time analysis, you use user-defined measures to define the quantities you want to look at through a series of time intervals, or time steps. For dynamic frequency and dynamic random analyses, you use user-defined measures to define a quantity you want to study at given frequency intervals, or frequency steps.

The fourth kind of dynamic analysis, dynamic shock, is time and frequency independent. The methods you use to define measures for a dynamic shock analysis are the same as those you use to define a stress, displacement, or rotation measure for a basic analysis.
