Button Link
The Button Link node () adds link to a button in an user input or selectable input.
To add a Button Link node, right-click a User Input or Selectable Input node and select it from the Buttons menu.
The Settings window has the following section:
Definition
From the Links from list, select Locally defined (the default), Built in, or External resources.
Locally Defined
Use this option to define a link to a locally defined menu under Definitions Library>Auxiliary Definitions, which you select from the Link list. Click the Add button () to display a quick menu where you can select a source to add in to the list and use it as the current reference. A Confirm Operation dialog box will appear and ask for confirmation if there is already a reference exist in the Link list. Click the Go to Source button to move to the referenced node in the Link list. Parameters appear that have been defined in the locally defined menu node, and you can edit their expressions in the Expressions column under Menu item parameters unless they have been defined as read only.
Built-In
Use this option to define a link to a built-in Java maker. From the Package list, select COMSOL Multiphysics or any other available package. Then select a link from the Link list (which by default is set to Not active). When you have selected an active link, you can also enter an icon file and a title in the Icon field and Text field, respectively. You can use this option to link from a Physics Builder maker to a Java maker. With a Java maker, you can have more control than with the Physics Builder maker.
External Resources
Use this option to define a link from an external resource, which you import from a file that you specify from the Imported file list. The Imported file list contains all Import nodes under External Resources. It is used by all link nodes in the Physics Builder, so the user interface is the same for all of them. Then select a menu or menu item from the Link list. Parameters appear that have been defined in the externally defined menu node, and you can edit their expressions in the Expressions column under Menu item parameters unless they have been defined as read only.
