Part of the book series: Notes on Numerical Fluid Mechanics (NNFM) ((NONUFM))

Summary

The Galerkin /least-squares finite element method is considered as a tool for solving singularly perturbed partial differential equations of elliptic type on adaptively refined grids. Local error estimates in subdomains away from boundary and interior layers are uniformly valid with respect to the small parameter. Boundary and interior layers can be resolved using locally anisotropic mesh refinement. Numerical examples are given for scalar convection-diffusion equations and for incompressible Navier—Stokes flow problems.
