An important feature of Ansys Forte is the ability to design parameter studies in which one or more simulation parameters or model options vary over a series of runs. Almost all of the simulation parameters and model options within the Ansys Forte Setup interface may be varied in this way by using the Parameter Study   button next to a parameter whose value is to be varied. Clicking this button launches a wizard that adds runs to the simulation using parameter values obtained from the wizard. The parameter values may be further edited in the Parameter Study utility that can be launched from the toolbar menu with the parameter-study button once a parameter variation has been defined. On the Editor panel where the nominal value is defined, the parameterized variable's label will be colored blue to indicate it is involved in a study.

The following examples illustrate some of the possible uses of the parameter study feature.

Varying a real number parameter:

To vary a parameter consisting of a numerical value (either dimensional or dimensionless), click the Parameter Study   button next to the parameter. A series of dialogs is displayed with which an initial interval of values may be generated. Once the wizard is finished, the values appear in a Run Table and may be edited further.

Varying a boolean parameter:

To vary a parameter consisting of a check box (boolean) click the Parameter Study button   next to that parameter. Select how the value will vary by using the pattern tool provided by the wizard. Once the wizard is finished, the values appear in a Run Table and may be edited further.

Varying a list selection:

Some parameters are provided as a drop-down list of two or more options. Vary these parameters by clicking the Parameter Study button   next to the selector and using the pattern tool provided by the wizard.
