摘要

The finite element program of the Navier-Stokes equation of the incompressible viscous flow is generated by Finite Element Program Generator (FEPG) successfully. In order to avoid the difficulties in computation, the operator splitting method is used to deal with the equation, in which the physical process described by N-S equation is decomposed into 2 processes: a diffusion process and a convection process. Virtual work formula of the diffusion equation and the convection equation are deduced. Convection equation is solved by the least square scheme. Numerical simulation about the incompressible viscous flow over a cylinder is made in the paper.
