Create a weight or volume objective

  1. On the Geometry Optimization dialog box, select Define Objective. Note: You can define only one objective for each optimization.

  2. From the Type list, select the type of response to evaluate. For example, if you want the goal of the optimization to be to minimize weight, select Weight.

  3. Choose the scope of the optimization by selecting a Category. To apply the optimization objective to the entire model, select Model Objectives. To apply the optimization objective to only one type of mesh in your model, select the type of mesh. For example, if your model contains 1D and 3D meshes, but you want the objective to be applied only to the 1D meshes, select 1D Objectives.

  4. From the Apply To list, select Body, Face, Edge, Point, or Curve.The option that you select sets a selection filter so that you can select the appropriate areas of your model to which you want to apply the objective.

  5. Select the areas of the model to which to apply the objective. If you set Categoryto Model Objectives, the objective is applied to the entire model automatically.

  6. In the Parameters group, select Minimize, Maximize, or Target. Depending on your selection, the objective is minimized, maximized, or it targets a value that you specify.

  7. If you selected Target, type a value in the Target Value box for the objective.

  8. From the Unit list, select the appropriate units of measure for the response. The optimization results are output in the selected units.

  9. Click Next to proceed to the Define Constraints step of the optimization setup.
