Using Approximation in Multi-Objective Design Studies
In a Multi-Objective Design Study, you have the ability to generate approximate evaluations of the design study goals. To generate approximation values, Creo Parametric uses the concept of a "response surface."
For a given point or set of points in the n-dimensional design space, the response surface gives approximate values of the design study goals. The approximate results are based on all conducted experiments.
Instead of conducting time-consuming regenerations, you can evaluate goals and create sensitivity studies based on approximated values. The approximated values allow you to quickly evaluate how design goals change for the specified values of the design variables. To use approximation values, click Tools > Approximation Value on the Multi-Objective Design Study dialog box.
In addition, you can create an approximation table derived from the master table. The approximation table gives you approximated values of the design study goals for the requested number of experiments. To create the approximation table, click Tools > Approximation Table on the Multi-Objective Design Study dialog box.
