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.
If you select multiple physics interfaces, the Dependent Variables section is not available.
To copy a physics interface with all its subnodes, right-click the physics interface node and choose Copy (or, for Windows users, click
Copy on the Quick Access Toolbar). You can then paste it in the same or a new COMSOL Desktop session by right-clicking a compatible
Component node and choosing, for example,
Paste Solid Mechanics (or, for Windows users, click, for example,
Paste Solid Mechanics on the Quick Access Toolbar).
It is also possible to insert physics interfaces from another COMSOL Multiphysics model into a model component. To do so, right-click a Component node and choose
Insert Physics from Model. An
Insert Physics dialog box appears where you can browse or type the path and name of the COMSOL Multiphysics model file from which you want to insert components in the
Model field. Select one or more of the physics interfaces in the model from the
Physics list and then click
OK to insert them into the current model. The list includes the space dimension for the physics interface so that you can select compatible physics interfaces.
