Title:　A total design of finite element schemes for flow problems

Abstract：　In the development of numerical schemes for flow problems, especially in the framework of the finite element method, there are some key issues, e.g., the approximation of the convection term, the choice of a finite element, and the mesh control, where the last one is not special for flow problems. This talk introduces a total design of finite element schemes for flow problems and related results and applications[1-5]. Refs. [1] M.M. Rasid et al.
