Nonlinear SSI

MASTODON is a highly-parallelizable, finite-element analysis code capable of three-dimensional nonlinear soil-structure analysis including the simulation of source-to-site wave propagation.

Risk Assessment

MASTODON is being developed to be a probabilistic risk assessment framework that enables not only deterministic analyses, but also probabilistic simulations.

Quality Assurance

MASTODON is being developed in accordance with the ASME NQA-1 safety software requirements.

A MOOSE-Based Application

MASTODON is built on the MOOSE framework and can efficiently solve problems using standard workstations or very large high-performance computers in different dimensions, including full 3D, 2D, 2D-RZ axisymmetric, layered 1D, and spherical 1D systems. Code reliability is paramount for the MOOSE framework, and MOOSE-based applications. MASTODON therefore employs a well-defined development and testing strategy in which, code changes are only merged into the repository after both a manual code review and an automated regression test have been completed.

MASTODON is developed by the Facility Risk Group at the Idaho National Laboratory by a team of computational scientists and structural and earthquake engineers, and is supported by various funding agencies including the United States Department of Energy.
