Domain, Boundary, and Pair Nodes for the Thermoviscous Acoustics, Boundary Mode Interface
The Thermoviscous Acoustics, Boundary Mode Interface has these boundary and pair nodes available from the Physics ribbon toolbar (Windows users), Physics context menu (Mac or Linux users), or right-click to access the context menu (all users).
In general, to add a node, go to the Physics toolbar, no matter what operating system you are using. Subnodes are available by clicking the parent node and selecting it from the Attributes menu.
In the COMSOL Multiphysics Reference Manual see Table 2-4 for links to common sections and Table 2-5 to common feature nodes. You can also search for information: press F1 to open the Help window or Ctrl+F1 to open the Documentation window.
The Continuity node with this physics interface is available as a pair boundary condition. This gives continuity in pressure, temperature variation, velocity and in the flux on a pair boundary between thermoviscous acoustics domains.
All of the boundary conditions available with the Thermoviscous Acoustics, Boundary Mode interface are the same as for the Frequency Domain and Transient version, and are described there (see the following list). The Thermoviscous Acoustics Model feature is described here. Some of the following nodes are available from the Mechanical Conditions and Thermal Conditions submenus (listed in alphabetical order):
