Edge Condition
The Edge Condition node () defines a feature that can only exist (have selections) on two levels below the geometric entity level of the physics (that is, it is only applicable for physics interfaces in 2D and 3D).
To add a Edge Condition:
On the Physics Interface toolbar, select Edge Condition 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.
