报告题目:Weak Galerkin Method and Its Applications

报告摘要Like the classic finite element methods, the weak Galerkin (WG) finite element methods are general methods for solving partial differential equations arising in science and engineering. The WG methods are flexible that general polygon/polyhedron meshes with hanging nodes can be used. This is a desired feature for adaptive mesh refinement.

The WG method is a natural extension of the classic Galerkin finite element method for the function with discontinuity. Therefore, the weak Galerkin methods have the flexibility of employing discontinuous elements and, at the same time, share the simple formulations of continuous finite element methods.

The purpose of this presentation is to introduce basis concepts of the weak Galerkin methods and their recent developments including new a posteriori estimators and applications on fluid dynamics.
