Abstract

A new class of preconditioners based on the adaptive threshold incomplete multifrontal factorization for indefinite and complex symmetric systems is developed. Numerical experiments consisting of the 3D Helmholtz equations, fluid–structure interaction and localization problems demonstrate the excellent performance of the preconditioner.
