ZEUS-NL
ZEUS-NL is the analysis and simulation platform of the MAE Center. It is a state-of-the-art 3D static and dynamic analysis platform specifically developed for earthquake engineering applications. Its extreme efficiency, accuracy, verification and user-friendly graphical user interface has made it easier than ever to undertake inelastic large displacement analysis of complex frames using the fiber approach, with a suite of material models and elements. ZEUS-NL is available free-of-charge. The MAE Center requires that publications including results from ZEUS-NL to include an acknowledgement of the MAE Center and the National Science Foundation (cooperative agreement reference EEC-9701785).
ZEUS-NL has become open source as of November 1st.
