Abstract [en]

A simple parallel numerical algorithm with P1/P1 velocity-pressure elements for solving the incompressible Navier-Stokes equations is proposed. In order to circumvent the Babuška-Brezzi condition (i.e. inf-sup condition), a velocity-pressure separation strategy following the idea of projection method is presented. Thus, the velocity and pressure terms are separated using operator-splitting, dividing the problem into two individual governing equations. The velocity equation is solved using an extension form of the position-state separation method (POSS), which has very good performance to solve convection-diffusion-reaction equations. The parallel computation of the method is easy to implement. Classical numerical experiments are conducted which show the efficiency, robustness and accuracy of the method.
