The Add Physics Window

The Add Physics window is similar to the Select Physics window accessed through The Model Wizard. It has the same physics interfaces available. This window is a quick way to add physics interfaces to models.

To open the Add Physics window:

• Right-click a Component node and choose Add Physics. • From the Home toolbar, click Add Physics • Select Windows>Add Physics. • From the Physics toolbar, click Add Physics .

• Right-click a Component node and choose Add Physics. • On the Model Toolbar click Add Physics . • On the Physics Contextual Toolbar, click Add Physics . • Select Windows>Add Physics.

The Add Physics toolbar button is a toggle button: Click it again to close the Add Physics window.

To Add Physics Interfaces to a Model Component

1	In the Add Physics window, either enter a Search term or navigate the tree to locate the physics interface to be added to the Component.

The tree organizes the available physics interfaces by application areas such as fluid flow, heat transfer, and structural mechanics. The physics interfaces found in the modules your license supports display in the different application areas. In some cases, licensing of a module adds physics interfaces to these application areas as well as attributes to existing physics interfaces, which are enhanced with additional functionality. The Recently Used branch lists the last five physics interfaces used in recent modeling sessions. You can also enter a text string in the search field and click the Search button to list all the interfaces with the search term.

The contents of the Add Physics window depends on the space dimension of the active model component. If there are no Component nodes in the model, the list of physics interfaces is empty.

2	Once a physics interface is clicked, review and optionally modify any dependent variable names in the Dependent variables section and, for some physics interfaces, specify the number of dependent variables.

When there is already a physics interface added to the Component, the existing Studies are listed under Physics interfaces in study. By default, the studies appear with a check mark () in the Solve column, which indicates that the study solves for the dependent variables in the physics interface. Click in the column to clear the check mark and exclude the physics interface from that study.

4	Click the Add to Component or Add to Selection buttons.

-	If Add to Component is selected, the physics interface is added to the Model Builder and becomes active in the entire model component’s geometry by default.

-	If Add to Selection is selected, the physics interface is added to the selected geometric entities in the Graphics window and a new node is added to the Model Builder. This is a method called preselection.
