The Pipe Connection, Diluted Species () multiphysics coupling couples a 1D pipe segment modeled with the Transport of Diluted Species in Pipes interface with a 3D domain modeled by Transport of Diluted Species interface.

Select the boundary that corresponds to the inlet/outlet of the 3D model coupled to Transport of Diluted Species in Pipes interface.

Select a Species transport interface and a Species transport in pipes interface to couple species transport.

There is an automatic search for possible adjacent geometrical objects. If you want to modify the selections, select the Manual control of selections checkbox. If you clear it, the selections will be replaced by the automatic ones.
