Edge Feature
The Edge Feature node () defines a feature that can only exist (have selections) on the edge geometric entity level, which represents lines in all space dimensions. This feature is normally only applicable in 3D (the default restriction), but can optionally be allowed in lower dimensions in special situations.
To add an Edge Feature:
On the Physics Interface toolbar, select it from the More Features menu.
Under Building Blocks, right-click Features and add it from the context menu.
Right-click the Physics Interface or Multiphysics Interface nodes to add this from the Features submenu.
The Settings window is almost identical to the Generic Feature, except that it does not include the Supported geometric entity levels list.
