Mr. Laydi, A 2-LEVEL NODAL METHOD FOR SOLVING THE STOKES EQUATIONS, Comptes rendus de l'Academie des sciences. Serie 1, Mathematique, 324(9), 1997, pp. 1075-1078
We solve the Stokes problem using a nodal method of low degree. We giv
e many two-level variational formulations in the standard non-conformi
ng finite element method. We give a calculus with a local basis of div
ergence free functions.
