Stokes Equations,ent the systems of the Stokes and Lamé equations as particular examples and define the ellipticity of such systems. Section 12.2 starts with the variational formulation of Stokes’ equations. The saddle-point structure is discussed in .12.2.2. Solvability of general saddle-point problems is analysed

The difference equations are complemented by the Dirichlet boundary condition. The equations of the resulting linear system correspond to the inner grid points, while the boundary data appear i
