A physics interface can have an Auxiliary Settings node () that contains a collection of settings for its physics interface that you usually do not need to change.

To add an Auxiliary Settings node, right-click the Physics Interface or Multiphysics Interface nodes and select it from the context menu. Also right-click the Auxiliary Settings node to add a Disable Allowed Study Types node.

The Settings window includes the following sections:

This section contains a table with the four columns: Property name, Input name, Default value, and Read only and hidden. The purpose of this table is to specify default values for the user inputs in properties of the physics interface. Of course the user inputs already have default values specified in their own features. So this functionality is a way to redefine those default values. A situation where this is useful is when two physics interfaces make use of the same property through a Property Link node. Then this setting makes it possible to have different default values of the user inputs defined under the property for the two physics interfaces.

Click to select either of the Not applicable on infinite element domain, Not applicable on perfectly matched layer domain, Not applicable on absorbing layer domain, Not applicable on moving domains, and Only applicable on layered material selections check boxes to make sure that the physics interface cannot be applied on a domain of the particular type.

In this section it is possible to select what standard features to remove from the context menu of the physics interface. Possible standard features are the following, which you can add by clicking the Add button () and selecting them from the dialog box that opens:

Select the Only hide features from context menus check box to only remove them from the user interface’s context menu but make it possible to open existing MPH-files that include any of the removed features.
