Beam Cross Section–Beam Coupling
Use the Beam Cross Section–Beam Coupling to transfer the cross section data from a Beam Cross Section interface to either a Beam Interface or a Pipe Mechanics interface. You need to use one such Beam Cross Section–Beam Coupling node for each type of cross section.
The Beam Cross Section–Beam Coupling node is only available with some COMSOL products (see https://www.comsol.com/products/specifications/)
Boundary Selection
Select the boundaries that represent the current cross section in the Beam Cross Section interface. This means that the selection should be identical to the selection in a corresponding Homogeneous Cross Section node.
Edge Selection, Beam
Select the edges of the beams that have the intended cross section.
Coupled Interfaces
Select the Beam Cross Section interface to couple.
Select the Beam interface to couple. This can be either a Beam interface or a Pipe Mechanics Interface.
