The Pressure Acoustics, Frequency Domain Interface has Domain, Boundary, Edge, Point, and Pair nodes, listed in alphabetical order, available from the
Physics ribbon toolbar (Windows® users),
Physics context menu (macOS or Linux® users), or right-click to access the context menu (all users). Continuity in the total pressure is the default condition on interior boundaries.
The Pressure Acoustics, Boundary Mode Interface also shares these nodes, with one additional feature described in
Boundary, Edge, Point, and Pair Nodes for the Pressure Acoustics, Boundary Mode Interface. For the Pressure Acoustics, Boundary Mode interface, apply the feature to boundaries instead of domains for 3D components.
