Open Source Software: MASTODON: Pioneering Multi-Hazard Analysis for Critical Infrastructure

The Department of Energy is seeking to commercialize the MASTODON software, a cutting-edge tool for modeling stochastic nonlinear soil-structure interactions. The software is designed to enhance the resilience of critical infrastructure against natural disasters. Key features of the software include: • Advanced NLSSI modeling for comprehensive simulations • Multi-hazard risk calculations for precise risk analysis • Nonlinear seismic wave propagation for high-fidelity simulations • Quantification of uncertainty for reliable risk assessments • MOOSE-based master application for computational efficiency and flexibility The software has various applications, including nuclear facilities, critical infrastructure, and dynamic probabilistic risk assessments.
