The Line Mass Source, Interface node adds mass flow originating from a tube of infinitely small radius to edges of layer interfaces of layered shells.
Set the interfaces on whose edges the Line Mass Source, Interface condition should be applied. These can be internal interfaces between layers or the top and bottom surfaces.
The available options in the Apply to list are
Top interface (the default setting),
Bottom interface,
Exterior interfaces,
Interior interfaces,
All interfaces, and
Selected interfaces. With the last option you can select any set of interfaces for a given layered material, by clearing the checkboxes corresponding to layer interfaces where the node should not be applied in the
Selection table. The top and bottom interfaces refer respectively to the upside and downside of the boundary, defined from the orientation of the normal vector. You can visualize the selected interfaces by clicking the
Layer Cross Section Preview (
) and
Layer 3D Preview (
) buttons.
Enter a value or expression for the source strength, N0 (SI unit: kg/(m·s)). A positive value results in mass injection from the line into the computational domain, and a negative value means that the mass is removed from the computational domain.
