About Design Improvement Studies

Design improvement studies test design variations for potential evolution of an existing design.

Parametric Design Improvement

A parametric design improvement study references existing content to create the basis for the study. You can reference the following types of content:

  • Product
  • Part
  • Fluid mechanics analysis case
  • Structural analysis case
If the study references a product or part, you can investigate how changes in design variables (such as part dimensions) affect attributes such as the mass or volume. If the study references an analysis case, you can investigate how the analyses affect the design performance. For example, you can observe key mechanical responses such as the maximum stress when the part is subjected to the loads in the structural analysis case.

Within a parametric design improvement study, you define design variables to specify the parameters you want to vary and their range of allowable values. Next, you define response variables, which allow you to monitor the result of the design variable changes. You can apply objectives (such as minimize, maximize, or a target value) to a response variable. You can also apply constraints, such as specifying the maximum allowable value for a parameter. Objectives and constraints are used to rank the designs and indicate which designs perform the best.
