Abstract : We design and analyze a new non-conforming domain decomposition method, named the NICEM method, based on Schwarz type approaches that allows for the use of Robin interface conditions on non-conforming grids. The method is proven to be well posed. The error analysis is performed in 2D and in 3D for P1 elements. Numerical results in 2D illustrate the new method.
Keywords : NICEM method Optimized Schwarz domain decomposition Robin transmission conditions finite element methods non-conforming grids error analysis NICEM method.
