                题目:A cell-centered finite volume method on locally refined composite Cartesian grids and its application in wetting problems

                时间2020年12月10号上午10:00-12:00

                地点:腾讯会议(ID:897 411 363)

                摘要: In this talk, I will present a cell-centered finite volume method on locally uniformly refined composite Cartesian grids. Unlike similar method on composite Cartesian grids (such as those proposed by McCormick Thomas 1986, Bramble-Ewing-Pasciak-Schatz 1988, Johansen-Colella 1998, Papac-HelgadottirRatsch-Gibou 2013 and Kriva-Handlovicova 2016), the method is derived in a very simple way based on finite Volume conservation of mass and flux. The finite volume stencils on composite grids are compact in both two and three space dimensions. I will also describe an efficient multilevel/multigrid (composite grid) iteration technique for the Poisson equation with the cell-centered finite method as well as its application in a three-dimensional wetting problem for moving contact lines. This is joint work with Xianmin Xu (CAS) and Zhongshu Zhao (SJTU).
