Testing Custom Physics Interfaces
Physics Builder files can contain several physics declarations that you can access from the Model Wizard. These physics interfaces are identical to built-in physics interfaces (the physics interfaces shipped with COMSOL Multiphysics), with the difference that their functionality is specified by your Physics Builder file.
The COMSOL Multiphysics software searches and uses the Physics Builder files that are located under the Development Files branch ().
1
Click the Physics Builder Manager button () in the main Physics Builder toolbar, or (on Linux and Mac) select Windows > Physics Builder Manager () to open the window.
2
Under Archive Browser, right-click the Development Files node to add new Physics Builder files to the list.
To remove a builder file from the list, select it and then right-click it and choose Remove Selected () from the context menu.
COMSOL loads all physics interfaces listed in the Development Files node when a new session is started. If a Physics Builder file is added during a session, COMSOL loads it and updates the list of physics interfaces.
If the Physics Builder file is changed on the file system by another session, you have to manually reload it to activate these changes.

Click the Register Development Files toolbar button () in the Physics Builder Manager window to reload all physics interfaces listed in the Development Files branch ().
