MIXED HYBRID DISCONTINUOUS GALERKIN METHODS FOR INTERFACE PROBLEMS
Tipo de evento: Seminário de Avaliação - Série A
In this work, both fitted and unfitted mixed hybrid discontinuous Galerkin (MHDG) finite element methods are proposed to solve the elliptic interface problems. For the unfitted case, we introduce the broken base functions (unnecessary to satisfy the jump conditions) on those elements which are cut across by interface. Unlike to the immersed interface methods (IIM), the two jump conditions are enforced weakly by the MHDG variational formulations. So, our unfitted interface MHDG can be applied more easily than IIM to general cases when the exact jump base function cannot be constructed. Numerical results on convergence and sensibilities of both interface position and different diffusion of the proposed methods are presented and discussed.
