Specifying a Solution Quantity for an Output Parameter

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

The Add/Edit Calculation dialog box lets you define the mathematical equation for one or multiple output parameters. To set up an output parameter:

1. In the Context section of the dialog box:

• Select the Report Type with a drop-down list containing the available types for this design.
• Select the Solution from the drop-down list. This lists the available setups and sweeps. As a minimum, the LastAdaptive solution is available.
• Select the Geometry from the drop-down list or select none (the default). This modifies the list of quantities available to the ones that apply to the specific geometry.
• When selecting a geometry, you may also be required to specify a point within the geometry where the calculation is performed.

2. Click Output Variables to open the Output Variables dialog box, in which you can create special output variables to be used in the output parameter.
3. Use the Calculation Expression field in the Trace tab to enter the equation for the output parameter. To enter an expression, type it directly into the field or use the Category, Quantity, and Function lists as follows:

• Select the Category. These depend on the Solution type and the design. This lets you specify the category of information used in the output parameter.
• Select a Quantity from the list. Available quantities depend upon the Solution type, as well as the Geometry and Category selection. Selecting a Quantity enters it into the Calculation Expression field.
• Select a Function to apply to the value in the calculated expression.
• For swept variables, click Range Function to open the Set Range Function dialog box to apply functions to the expression that apply over the sweep range.

4. The Calculation Range tab applies to swept variables and lets you specify the range of the sweep over which to apply the calculation.
5. When you obtain the desired Calculation Expression, click Add Calculation to add the entry to the calculation table in the Setup Sensitivity Analysis dialog box. To add multiple entries to the table, change the Calculation Expression and click Add Calculation.
6. To update or edit a selected cost function, enter the desired Calculation Expression and click Update Calculation.
7. Click Done to return to the Setup Sensitivity Analysis dialog box.
   Note:

   The specified solution quantity must be able to be evaluated to a single, real number.
