Iterative Rational Krylov Algorithms for model reduction of a class of constrained structural dynamic system with Engineering applications
Xin Du, M. Monir Uddiny, A. Mostakim Fonyz +2
This paper discusses model order reduction of large sparse second-order index-3 differential algebraic equations (DAEs) by applying Iterative Rational Krylov Algorithm (IRKA). In g…
