Use a Solid Connection node for connecting beams to solids in 2D models. To complete the connection, a corresponding
Beam Connection node must also be added in the Solid Mechanics interface. The
Solid Connection node can be added to either points or boundaries.
Select a Connection type —
Softened or
Simplified. When using
Softened (the default), three extra degrees of freedom are added to each selected point. This allows for a more accurate description of the transition, but the model can in some cases become underconstrained if the mesh on the solid is very coarse. The
Simplified version of the connection just adds constraints to the boundary of the solid, and will in general cause local disturbances of the stress field.
When using the Solid Connection node for a boundary, the connection is intended for placing a beam as a stiffener or cladding along the boundary of a solid. No other settings than the boundary selection are required.
