Setting Approximations Preferences

You can determine the technique that Isight uses each time you first create an approximation. The default technique is also used each time you first add an Approximation component to the simulation process flow.

  1. From the Design Gateway or Runtime Gateway Edit menu, click Preferences.

  2. Click Approximations and in the Default Technique list, select the technique that Isight always uses when you first create an approximation. By default, Response Surface Model is selected. For more information about the available techniques, see Creating and Using Approximations.

  3. Click Warn when a component with approximations is changed, if desired.

    If you select this option and an approximation has been defined for a component, a warning message appears when that component’s editor is closed when you click OK or Apply. The warning states that changes to the component may invalidate the existing approximations, and you are asked to confirm the change. By default, this option is selected.

  4. Click Warn when initialization is canceled due to model change, if desired.

    If you select this message, a warning message appears when a different model is selected while Isight is initializing an approximation. The warning states that the initialization has been canceled because of the change. By default, this option is selected.

  5. Click OK to save your changes and to close the Preferences dialog box.
