ROMULIS 1.01.00

Lacayo, Robert M.; Brake, Matthew R.

The Reduced Order Modeling Unlimited Localized Interface Simulator (ROMULIS) is a set of toolbox scripts in MATLAB designed to perform nonlinear transient integration on a system of reduced order st ructural models that interact with each other at localized interfaces. ROMULIS is meant to provide a us er-friendly interface for applying the latest developments in numerical techniques and modeling in structural dynamics analysis while also giving the freedom to implement new technologies from forthcoming research. This report documents how to use and interpret the toolbox sc ripts. The theory behind th e code is given, followed by a manual for interacting with the scripts to perform simulations. Lastly, a high-level introduction that explains how the scripts in teract with each other is given for aspiring developers.
