Domain, Boundary, Edge, Point, and Pair Nodes for the Fluid-Structure Interaction Interface
The Fluid-Structure Interaction Interface has these domain, boundary, edge, point, and pair nodes, listed in alphabetical order, 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.
These nodes are unique to the physics interface and described in this section:
•
Initial Values
•
Wall
•
Fluid-Solid Interface Boundary
•
If you also have a CFD Module or Heat Transfer Module, the Interior Wall boundary condition is also available and is documented in the CFD Module User’s Guide or Heat Transfer Module User’s Guide, respectively. This boundary condition is useful for avoiding meshing of thin wall structures by using no-slip conditions on interior curves and surfaces.
•
With the addition of a module that enhances various fluid flow interfaces, the Line Mass Source and Point Mass Source features are also available and described in the COMSOL Multiphysics Reference Manual.
These nodes are described for the Solid Mechanics interface:These nodes are described for the Laminar Flow or Moving Mesh interfaces in the COMSOL Multiphysics Reference Manual (listed in alphabetical order):
