Numerical Study Of The Incremental Unknowns Methods On Floated Grid

In this paper.Through numerical experiments of two-dimensional second-order Dirichlet boundary-value, Simplified Linear incompressible Navier-Stokes equation and nonlinear evolutionary equation.we define incremental unknowns on model of discretization of figure(3.2) ,we define this model is floated grid, it is efficiency that numerical test of incremental unknowns have been operated by three problem on the top.The iteration steps of the methods ,in this article,is almost equality with classical incremental unknowns in like problem and like precision.but the discretization of the article is more simply than the classical grid, as well as the matricial framework of article is more simply than classical incremental unknowns. The method of the article is efficient algorithm.
