Structure provides the following dynamic analyses:

User-defined measures are especially important for dynamic analyses, where you want to study the model's behavior over a time range, at a point in time, or as a function of frequency. In fact, 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), over a range of time, or at a point in time. 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 method you use to add user-defined measures for dynamic analyses differs slightly from the one you use for a basic analyses. The main difference is that the measures for most dynamic analyses require you to define the measure in terms of time or frequency.

The exception is the measures for dynamic shock analyses, which are 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. Thus, to learn about dynamic shock, see Dynamic Shock Analysis.

When you define a user-defined measure for dynamic analyses, you specify a measure that involves a time- or frequency-based calculation. In defining this type of measure, you indicate the quantity, component, spatial evaluation method, and time or frequency evaluation method. Creo Simulate provides several options for each of these aspects of the measure, as follows:
