Fluid/Solid coupling method using FDM

The lithosphere/asthenosphere interaction in subduction zones can be viewed as a fluid/solid coupling problem. Therefore, I have developed a code which couples a standard FE Stokes solver and the FE solid solver ADELI ([1],[2]). The coupling is performed by the use of a Fictitious Domain Method (see [3] for a complete description of the algorithm). Below is a simplified description of the strategy :
