Application of a Krylov subspace method for an efficient solution of acoustic transfer functions

Reduced-order methods for dynamic problems in topology optimization: A comparative study

“…For most dynamic problems, the systems are second-order, and as a consequence, the second-order Krylov subspace method was developed. It has successfully been applied to frequency space analysis of large-scale structures 45 , acoustic systems 45,46 , etc., but not in the context of topology optimization.…”
