The University of Texas has developed software to predict noise and vibration in automobiles. Automated Multilevel Substructuring (AMLS) was copyrighted in 2000. The software divides the model of a car into sub-structures and solves them independently. A model that originally would have had 1e6 DOFs, can be reduced into 20 levels of 10e3 DOFs.
