Preconditioners for solving the indefinite linear system for higher order H (curl) discretisations

This paper presents numerical results for a preconditioning technique for the iterative solution of the indefinite linear system of equations obtained when a higher order H (curl) conforming finite element approximation is adopted for the vector wave equation. Numerical results are presented for a m...

Zusammenfassung:This paper presents numerical results for a preconditioning technique for the iterative solution of the indefinite linear system of equations obtained when a higher order H (curl) conforming finite element approximation is adopted for the vector wave equation. Numerical results are presented for a model problem that includes a singularity at the origin and dicretisations that include graded meshes and uniform p. (© 2008 WILEY‐VCH Verlag GmbH & Co.
