Abstract

We propose Nitsche’s method for discontinuous parameters that takes the local mesh sizes of the non-matching meshes carefully into account. The method automatically adapts to the changing material parameters and mesh sizes. With continuous parameters, the method compares to the classical Nitsche’s method. With large discontinuity, the method approaches assigning Dirichlet boundary conditions with Nitsche’s method.
