Abstract:
We consider an Extended Finite Elements method to handle the case
of composite independent grids that lead to untted meshes. We detail
the corresponding discrete formulation for the Poisson problem with dis-
continuous coecients. We also provide some technical details for the 3D
implementation. Finally, we provide some numerical examples with the aim
of showing the eectiveness of the proposed formulation.
