Setting Up an Output Parameter
Following is the general procedure for adding an output parameter to a sensitivity setup:
- Under the Calculations tab of the Setup Sensitivity Analysis dialog box, click Setup Calculations to open the Add/Edit Calculations dialog box.
- In the Add/Edit Calculations dialog box, set up output parameter calculations to be evaluated for sensitivity.
- To modify the solution from which the output parameter is to be extracted, click in the Solution column and select from the options in the pop-up list.
- You can modify the Calculation specified by clicking on the output parameter in the table and selecting Edit.
- For output parameters based on swept variable, you must choose a single value in the Calculation Range at which to evaluate the output parameter.
- If the output parameter is based on a swept variable, in the Calculation Range column, set the value of the variable at which the output parameter is to be computed.
- If you have more than one output parameter,
select Primary
Output if you want Optimetrics to use the output parameter
to base its selection of solved design variations.
Note:
During a sensitivity analysis, the design variations that Optimetrics selects to solve are close to the design point, but not so close that numerical noise (from the finite element mesh) affects the analysis. The algorithm that Optimetrics uses to determine the design variations to solve must be based on only one output parameter and that output parameter's numerical noise. If you have defined more than one output parameter, be sure to select Primary Output for the output variable on which you want the selection of design variations to be based.
