CoNCMOR: Coherent Nodal Cluster Model Order Reduction

Library for constructing the "Ritz" transformation matrices for the Coherent Node Cluster model-order reduction.

Based on the paper accepted for publication as NME-Jul-19-0522.R1 - Rapid Free-vibration analysis with Model Reduction based on Coherent Nodal Clusters, in the International Journal for Numerical Methods in Engineering, 03/03/2020. Authors: Krysl, Petr, and Sivapuram, Raghavendra; both of University of California, San Diego , Jacobs School of Engineering Department of Structural Engineering; and Abawi, Ahmad, of Heat, Light, and Sound Research, Inc.

This package works with FinEtools. If you need the model reduction package to work with Elfel, please use CoNCMOR2.
