The Heat Transfer Interfaces have domain, boundary, edge, point, and pair nodes and subnodes (including out-of-plane and layer features) available. These nodes, listed in alphabetical order in this section, are available from the Physics ribbon toolbar (Windows users), from the Physics context menu (Mac or Linux users), or by right-clicking to access the context menu (all users). Subnodes are available by right-clicking the parent node and selecting it from the Attributes menu.
