OOF2: The Manual

The Interfaces Page allows a user to define interfaces on the Microstructure. The layout of the page is similar to the Skeleton Boundaries Page.

Interfaces are similar to skeleton or mesh boundaries in many respects. When a mesh is created, an element is defined for each edge belonging to an interface. Each edge element, or edgement, can contribute to the stiffness matrix if a material with interface properties such as surface tension is assigned to the interface. Certain boundary conditions can also be assigned directly to interfaces. One can also go to the Skeleton Boundaries page and create a new skeleton boundary based on an interface definition. In contrast to normal skeleton boundaries, interfaces (and skeleton boundaries based on these interfaces) may correspond to a disconnected set of edges in the Mesh.

Figure 3.14 illustrates the Interfaces Page. The Microstructure Chooser at the top selects the Microstructure whose interface definitions are to be edited. The Interface List Pane on the left lists all of the interfaces defined in the current microstructure, and provides buttons for editing them. The Interface details pane on the right shows information about the interface selected in the list.
