Global Spatial Evaluation Methods
In working with the global spatial evaluation methods, consider the following points:
• Because Creo Simulate must recover data for each plotting grid point at every time step or frequency step, choosing any of the global spatial evaluation methods may result in a time-consuming dynamic analysis run.
For example, if you select Maximum for a displacement measure in a dynamic time analysis, the maximum displacement is calculated at every plotting grid point. The software repeats this process for each time step.
However, bear in mind that once you define a global measure using one type of spatial evaluation, an insignificant amount of additional time is required to calculate a different measure that uses the same type of spatial evaluation.
In other words, if you specified Maximum as a spatial evaluation method for a von Mises stress measure as well as a maximum principal stress measure, there would be no appreciable time difference between running a dynamic analysis that used only one of the measures and running an analysis that used both measures.
• If you select stress or strain as the quantity, there is an additional option menu that enables you to determine whether the software considers the entire model or samples various points within a specified radius of a model location. The latter type of measure is called a
Near Point measure. For more information on
