摘要: 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 can be resolved using locally anisotropic mesh refinement. Numerical examples given scalar convection-diffusion incompressible Navier—Stokes flow problems.
