The Application Builder and the Application Tree
The Application Builder window on the COMSOL Desktop contains the Application tree. This tree displays nodes from the Application Builder’s data structure and nodes from the embedded model. All nodes from the embedded model behave exactly like the nodes in the Model tree when working with the Model Builder. The Application tree also includes a root node of the application and the following branches under the Root node:
The Root node () in the Application Builder is similar to the Root node in the Model Builder, but it also contains an Application sections with settings specific to applications; see The Root Settings and Properties Windows in the COMSOL Multiphysics Reference Manual for more information.
