Gluing of a non-matching interface between dissimilar meshes is one of challenging tasks in computational mechanics. Interface element method (IEM) has been developed by using an appropriate interpolation scheme on interface regions between partitioned finite element meshes. The continuity of displacements at the interfaces is satisfied exactly, and the completeness of the shape functions for the interface elements provides a reasonable transfer of strain fields through the non-matching interfaces. Moreover, the compatibility of the interface elements and the finite elements provides a seamless connection of dissimilar meshes. The construction of the interface elements makes it possible to connect dissimilar meshes with arbitrarily curved non-matching interfaces in three dimensions.
