Partially Penalized Immersed Finite Element Methods For Elliptic Interface Problems
Tipo de evento: Seminário LNCC
This talk presents new immersed finite element (IFE) methods for solving the popular second order elliptic interface problems on structured Cartesian meshes even if the involved interfaces have nontrivial geometries. Closely related to the linear and bilinear IFE methods in the literature which are based on the traditional Galerkin formulation, these new IFE methods contain extra stabilization terms introduced only at interface edges for the purpose penalizing the discontinuity in IFE functions. The error estimation shows that these IFE methods converge optimally in an energy norm. Numerical examples are provided to demonstrate that these new IFE methods outperform IFE methods published before according to the accuracy in the vicinity of the interface.
