Porous-Structure Boundary
The Porous-Structure Boundary coupling () is used to couple a Porous Domain (Biot’s model) domain from the Poroelastic Waves interface to a Solid Mechanics, Shell, Membrane, or Multibody Dynamics interface. At the solid-porous boundaries continuity of the displacement field is applied.
In 2D components it is possible to define the out-of-plane thickness for the structural interfaces while in acoustics this thickness effectively is unity (set to 1 m). A rescaling is automatically performed for the pressure load to account for this difference in interpretation in 2D.

The default Name (for the first multiphysics coupling feature in the model) is psb1.
Coupled Interfaces
This section defines the physics involved in the multiphysics coupling. The Porous media and Structure lists include all applicable physics interfaces. See the Coupled Interfaces in Acoustic-Structure Boundary for details.
