We introduce in this paper a new direction splitting algorithm for solving the incompressible Navier-Stokes equations. The main originality of the method consists of using the operator (I À @ xx )(I À @ yy )(I À @ zz ) for approximating the pressure correction instead of the Poisson operator as done

Fully discretized incompressible Navier-Stokes equations are solved by splitting the algebraic system with an approximate factorization. This splitting affects the temporal convergence order of velocity and pressure. The splitting error is proportional to the pressure variable, and a simple analysis
