3.0 - MOOSE: Enabling massively parallel multiphysics simulations

TLDR

The growth in MOOSE's capabilities and downstream applications is reflected in the growth of the community. This paper reports on these developments, with several major released features, new physics modules, and key improvements to the user experience and simulation workflow. The authors describe the release of new physics modules and user experience improvements that enable massively parallel multiphysics simulations. The development of MOOSE has accelerated, with over 2,100 pull requests merged in 30 months, nearly fifty contributors across a dozen institutions, user support growing to nearly 50 daily interactions, and new simulation projects for advanced nuclear reactors and fusion devices driving significant capability expansion.

Abstract

The development of MOOSE has kept accelerating since the last release, with over 2,100 pull requests merged over the last 30 months that involved nearly fifty contributors across close to a dozen institutions internationally. The growth in MOOSE's capabilities and downstream applications is reflected in the growth of the community. User support provided on the GitHub discussions forum has steadily increased to nearly 50 daily interactions. New simulation projects, notably to model advanced nuclear reactor and fusion devices, are driving a significant expansion of the capabilities. This paper reports on these developments, with several major released features, new physics modules, and key improvements to the user experience and simulation workflow.
