Add the Structure–Pipe Connection multiphysics coupling node () to create transitions between edges modeled using the Pipe Mechanics interface and domains or boundaries modeled using the Solid Mechanics or Shell interfaces in 3D.

The multiphysics coupling is intended for situations where the cross-sectional properties match on both sides of the connection. It can be considered as an extension to the transition type couplings in Solid–Beam Connection and Shell–Beam Connection that also accounts for radial deformation of the pipe caused by the fluid pressure and the temperature difference over the cross section.

Select Structure — Solid Mechanics or Shell.

Select the Pipe Mechanics interface to couple.

The Search method shows available mesh search methods for the mapping operator between the source and destination boundaries.

The Closest point method is the default and most robust search method. The Manual method is computationally efficient but its robustness is determined by the Search distance and the Extrapolation tolerance.
