  - Optimization Overview
    Optimization will find the most effecitve design for each design space in a model in response to the applied loading conditions on that model. You can run several different types of optimization including topology, topography,gauge, and PolyNURBS shape optimization.
  - Design Spaces for Optimization
  - Run Options: Local vs. Remote
    Choose whether to run jobs locally or on a remote job server.
  - Run Optimization
    Define and run a topology, topography, or gauge optimization using the Run Optimization tool.
    - Set Up and Run an Optimization
      To run an optimization, select the Run Optimization tool, choose a run type and objective, and click Run.
    - Optimization Types
      Several different types of optimization are available in Inspire, including topology, topography, and gauge optimization.
    - Optimization Objectives
      When running an optimization, your objective may be to maximize stiffness, maximize frequency, or minimize mass. Different objectives are available based on the type of optimization selected.
    - Optimization Constraints
      Most optimization constraints are applied using the Run Optimization window. The constraints that are available change based on the optimization type and objective.
    - Optimization Options
      In addition to selecting an optimization type, objective, and constraints, you can also select from a variety of additional options when running an optimization.
      - Speed/Accuracy (optimization)
        The Speed/Accuracy option allows you to prioritize speed or accuracy when running an optimization.

Speed/Accuracy (optimization)

The Speed/Accuracy option allows you to prioritize speed or accuracy when running an optimization.

You can define the Speed/Accuracy in the Run Optimization window. For optimization, the Speed/Accuracy setting is set to Faster by default. In the vast majority of cases, this setting is sufficient to obtain good conceptual designs. The More Accurate setting is really only necessary when a great degree of accuracy is required for frequency constraints. Selecting More Accurate will significantly increase total run time.

On the Strucutres ribbon, click Run Optimization on the Optimize icon.

Tip: To find and open a tool, press Ctrl+F. For more information, see Find and Search for Tools.
Select an optimization Type and Objective. The options in the Run Optimization window will change based on which options you select.
Click the button next to Speed/Accuracy and select Faster or More Accurate.
Set the remaining options for the run as desired.
Click Run to start the optimization. While the optimization run is in progress, you can monitor its status using the Run Status window.
When complete, double-click the name of the run to view the results.
