Solución de N.S. Incompresible a través de Funciones de Forma Bilineales para las Variables Primitivas

Abstract

Frecuently the works dealing with the solution of the incompresible Navier Stokes equations by finite element methods use mixed-order interpolation scheme. Also, presure and velocities are often simultaneously obtained.
This paper presents an equal-order interpolation method that does not exhibit spurious modes. Momentum and continuity equations are solved by means of a segregated solution scheme.
Two examples used by a number of researches are presented for comparison purposes.
