Preconditioned iterative methods for nonselfadjoint or indefinite elliptic boundary value problems

Conference ·
OSTI ID:6191390
We consider a Galerkin-Finite Element approximation to a general linear elliptic boundary value problem which may be nonselfadjoint or indefinite. We show how to precondition the equations so that the resulting systems of linear algebraic equations lead to iteration procedures whose iterative convergence rates are independent of the number of unknowns in the solution.
