Research program in iterative solution and finite element analysis in computational mechanics. Annual progress report, 1983
The second year of research concerning the theory and use of iterative methods in finite element approximation of boundary-value problems is covered. Significant progress has been made, especially in the development of a new technique, termed the local elliptic projection procedure, for use in adaptive finite element mesh refinement and iterative solution; analysis of errors for domain truncation to evaluate far field boundary conditions on finite domain approximations to a fully infinite domain; analysis of certain nonlinear literative methods for penalty finite element approximation of Navier-Stokes problems; development of a local element-oriented (block) iteration scheme and an algorithm for vector processors; the vectorization of the ITPACK software package; other work on vectorization; and the iterative solution of nonsymmetric linear systems.
