Nitsche- and Fourier-finite-element method for the Poisson equation in axisymmetric domains with re-entrant edges
The paper deals with a combination of the Fourier method with the Nitsche-finite-element method (as a mortar method). The approach is applied to the Dirichlet problem of the Poisson equation in threedimensional axisymmetric domains with reentrant edges generating singularities. The approximati...
