Stability of the P1nc-(P0+P1) element

Résumé

We solve the Stokes problem numerically. We analyse the P1nc-(P0+P1) mixed finite element method which exhibits interesting numerical features. However, only an incomplete proof of the inf-sup condition is available. We prove here this condition and the stability of the method.
