Efficient Iterative Algorithms for the Stochastic Finite Element Method with Application to Acoustic Scattering
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
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 ...
