About this document

Krylov Methods for FEM Model Reduction by gorot1 is a document available to read on EtoBox.

This document discusses model order reduction methods for large finite element models used in machine tool simulations. It focuses on using Krylov subspace methods to reduce the order of the state space models generated from FE analyses. The key points are: 1) FE models result in very large sparse dynamical systems that are computationally expensive to simulate directly. Model order reduction aims to find a lower order approximation that captures the essential dynamics. 2) Krylov subspace methods work by
