On a Class of Preconditioners for Solving the Discrete Helmholtz Equation
In this paper, we analyse and implement preconditioners for efficiently solving the discrete Helmholtz equation. The preconditioners are based on definite versions of the Helmholtz equation. The computational performance with Bi-CGSTAB is presented for a 2D homogeneous model problem.
