After historical remarks in Section 8.1 we introduce the Ritz–Galerkin method in Section 8.2. The basic principle is the replacement of the function space . in the variational formulat

Starting from the variational formulation, one obtains a strong formulation for each subdomain in which the coefficients are smooth. In addition, one gets transition equations at the inner boundary .. Finite-element methods should use a triangulation which follo

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 in the right– hand side of the system.
