Optimetrics > Adding a Cost FunctionA cost function can include one or more goals for an optimization analysis. Optimetrics manipulates the model’s design variable values to fulfill the cost function. Following is the general procedure for adding a cost function with a single goal. 1. Under the Goals tab of the Setup Optimization dialog box, click Add. A new row is added to the Cost Function table. 2. In the Solution column, click the solution from which the cost function will be extracted. 3. Specify a solution quantity on which to base the cost function goal. 4. In the Calc. Range text box, set the range within which the cost function will be computed. 5. In the Condition text box, click a condition from the pull-down list: ![[spacer]](1p.gif){kind=small}
6. In the Goal text box, type the value of the solution quantity that you want to be achieved during the optimization analysis. If the solution quantity is a complex calculation, the goal value must be complex; two goal values must be specified. 7. Optionally, if you have multiple goals and you want to assign higher or lower priority to a goal, type a different value for the goal’s weight in the Weight text box. The goal with the greater weight is given more importance. If the goal is a complex value, the weight value must be complex; two weight values must be specified. The weight value cannot be variable dependent. During the cost evaluation process, an updated progress message will be displayed in the progress window. The optimization will stop when the solution quantity meets the acceptable cost criterion. The topics for this section include: Specifying a Solution Quantity for a Cost Function Goal Specifying the Calculation Range of a Cost Function Goal
