Participants : Roland Becker, Daniela Capatina, Julie Joie, Didier Graebling.

Based on the library Concha we have implemented a three-field formulation with unknowns (u, p, ) for the two-dimensional Navier-Stokes equations, based on nonconforming finite elements. The extension to the Giesekus-model for polymers has been achieved, see Section  6.4 . In the case of Newtonian flows, the extra-tensor can be eliminated in order to reduce storage and computing time. This procedure serves as a pre-conditioner in the general case. The aim is to provide software tools for the problems in Section  4.2 .
