Design Variables Manager

The icons in the simple toolbar at the upper right corner of the manager allow you to create new design variables, preview a change in parameter values, or delete a design variable. The Preview option opens a dialog box where you can enter values or use a slider to change the parameter and observe its impact on the model. When you close the preview dialog, the design variable returns to the value set in the manager.

To display the Design Variables Manager, click Design Variables Manager from the Design Variables section of the action bar. You can search and filter the view based on variable names.

The manager displays the selection status, name, value, minimum, maximum, and step size for each parameter available in a study. You cannot select read-only parameters, such as those defined by formulas, or those calculated by the app, such as the mass and inertia of a part.

A lock symbol is displayed for the minimum and maximum settings if a range has been specified for that parameter. You can edit any field that does not have a lock symbol. You can clear a row to exclude a parameter from the study. You can change the minimum and maximum to control the range of a variable used in the study. If you do not specify an range, a default range is applied.

You can specify a step size to define the list of allowable values for the variable. The default step size is continuous; therefore, real values can take any value between the minimum and the maximum, and integers can take any integer value between the minimum and the maximum. If you specify a step size, then only values starting with the minimum and incrementing by the step size are eligible to be used in the study. The exact values selected for each design variable are determined by the number of design points and sampling technique that you specify when you configure the study.
