This work addresses some issues in the embedded interface method for the conjoined interface between fluid and structure domains in two-dimensional Fluid-Structure Interaction (FSI) coupled problems. Our approach uses Lagrange multipliers to enforce the kinematic condition along the interface between the non-matching overlapping meshes of the structural and fluid fields in an alternative to the usual Arbitrary Lagrangian Eulerian (ALE) approaches. The main idea of our work is to discretize the embedded interface independently of the fluid and solid mesh, using discontinuous interpolating functions. The purpose of this is to avoid numerical instabilities and to simplify the implementation. In order to illustrate the method's applicability, steady and unsteady simulations of incompressible viscous flow with a moving interface as well as FSI problems involving large structural displacements were performed.
