Efficient Iterative Algorithms for the Stochastic Finite Element Method with Application to Acoustic Scattering
(2002-12-19)
In this study, we describe the algebraic computations required
to
implement the stochastic finite element method for solving problems in
which uncertainty is restricted to right hand side data coming from
forcing ...
A Multigrid Method Enhanced by Krylov Subspace Iteration for Discrete Helmholtz Equations
(1999-08-27)
Standard multigrid algorithms have proven ineffective for the solution of
discretizations of Helmholtz equations. In this work we modify the standard
algorithm by adding GMRES iterations at coarse levels and as an outer ...
