### 3.13.5 Tied Interfaces

A tied interface can be used to connect two non-conforming meshes [40]. A tied interface requires the definition of both a primary and a secondary surface. It is assumed that the nodes of the primary surface are connected to the faces of the secondary surface. The following control parameters need to be defined:
