Implementing Automated Multi-Level Substructuring In Nastran Vibroacoustic Analysis 2001-01-1405

Automated Multi-Level Substructuring is a new method for analyzing vibrations of complex structures. Finite element models are automatically divided into thousands of substructures, and response is represented in terms of substructure modes. This method reduces the analysis burden greatly by reducing the computation that must be done, enabling workstations and multiprocessor computing platforms to be used, and reducing disk space requirements and job turnaround time. This paper explains how this method has been implemented for production use in the automotive industry, in conjunction with Nastran software.
