HFSS15: Specifying a Solution Quantity for a Cost Function Goal

Specifying a Solution Quantity for a Cost Function Goal

When setting up a cost function, you must identify the solution quantity on which to base each goal. Solution quantities are specified by mathematical expressions that are composed of basic quantities, such as matrix parameters, and output variables.

1. Add a row (a goal) to the cost function table:

a. Under the Goals tab of the Setup Optimization dialog box, click Add.

A new row is added to the Cost Function table.

b. In the Solution column, click the solution from which the cost function is to be extracted.

2. In the Solution text box, click the solution from which the solution quantity is to be extracted.

3. In the Calculation text box, specify the solution quantity in one of the following ways:

• If you know the syntax of the mathematical expression or the output variable's name, type it in the Calculation text box.

• If you want to create an output variable that represents the solution quantity, do the following:

a. Click Edit Calculation.

The Output Variables dialog box appears.

b. Add the expression you want to evaluate, click Done.

c. Click Done to close the Output Variables dialog box.

In the Setup Optimization dialog box, the most recently created output variable appears in the Calculation text box.

d. To specify a different defined output variable, click the Calculation text box. It becomes a pull-down list that displays all of the defined output variables. Click an output variable from the pull-down list.
