Optimization

Home Screen Process Flowchart

1. Select the Optimization box.                                                                 

A window Optimization shall open.

Add Objective

 

1. Select the Objectives tab.
2. From Responses select acceleration as the objective.

Define Objective

1. Since the acceleration is negative, select the option Maximize the Objective Function (instead of minimize)

• For Weight leave the default 1. If you have several objective functions, you may assign weight to each one according to their importance.

Add Constraints.

1. Select the Constraints tab.
2. From Responses select mass and displacement as the Optimization constraints.                         

Set bounds for Constraints.

1. Select Set Upper Bound for mass at 1,8.
2. Select Set Upper Bound for displacement at  241.

Optimization Algorithm.

1. Select the Algorithms tab. Here, the algorithm used for the optimization on the metamodel can be selected.

• Make sure that the radio button for Adaptive Simulated Annealing (ASA) is selected and Switch to LFOP is checked. These are the default settings.     
  

2. Select the OK button to proceed.
