 The technique we describe here is presented in the literature using one of many names:
-the **immersed finite element method**, the **fictitious boundary method**, the

 that the discretization of the two grids and of the two finite element spaces
 are kept completely independent. This technique is particularly efficient for
 the simulation of fluid-structure interaction problems, where the configuration
