WebApr 15, 1997 · The LBB stability conditions of the two proposed methods are checked by using the macroelement technique. 1. Introduction The recent researches [1-3] reveal that the stabilized finite element methods (or Galerkin-least- squares methods) are equivalent to the standard Galerkin methods with some proper 'bubble functions'. WebWe discretize the velocity field with continuous piecewise linear functions enriched by bubble functions, and the pressure by piecewise linear functions. We show that this element satisfies the usual inf-sup condition and converges with first order for both velocities and pressure. incident at indian springs cheyenne https://lixingprint.com
