Lesaint-Raviart method

Upwinding methods as well as discontinuous Galerkin (Lesaint-Raviart) methods have l n introduced to account for transport terms in the diiferential constitutive equation [62]. 

In this paragraph, a Lesaint-Raviart method is presented. A Newton algorithm allowing fixed values of the viscoelastic extra-stress components outside the finite elements is used. A fixed-point algorithm on those exter extra-stress components is also involved. Tffis quasi-Newton method needs a storage requirement of the same size as that related to a classical decoupled method, but allows improved convergence [39]. 

A discontinuous Galerkin Q method based on the Lesaint-Raviart techniques was used in [16]. An interesting point in this formulation is the use of an element by element basis if a...

The Lesaint-Raviart (discontinuous Galerkin) method [62] is based on discontinuous approximations of the extra-stress components and is characterized by an element per element treatment of the constitutive equation. This leads to the introduction of a stress step in the Galerkin formulation, from the preceding...
