✦ Synopsis
In this paper, order one ®nite elements together with Galerkin least-squares (GLS) methods are used for solving a three-®eld Stokes problem arising from the numerical study of viscoelastic ¯ows. Stability and convergence results are established, even when the solvent viscosity is small compared to the viscosity due to the polymer chains. An iterative algorithm decoupling velocity±pressure and stress calculations is proposed. The link with the modi®ed elastic viscous split stress (EVSS) method studied in (M.
