MOOSE: Multiphysics Object Oriented Simulation Environment

  • A framework for solving computational engineering problems in a well-planned, managed, and coordinated way

  • Designed to significantly reduce the expense and time required to develop new applications

    • Maximize Science/$
    • Designed to be easily extended and maintained
    • Efficient on both a few and many processors
    • Provides an object-oriented, pluggable system for defining all aspects of a simulation tool.

Solves Problems that Challenges Others

Strong Coupling: better agreement between MOOSE and reference

Weak Coupling: excellent agreement between MOOSE and operator-split

MOOSE Software Quality Practices

  • MOOSE follows an NQA-1 (Nuclear Quality Assurance Level 1) development process.
  • All commits to MOOSE undergo review using GitHub Pull Requests and must pass a set of application regression tests before they are available to our users.
  • All changes must be accompanied by issue numbers and assessed an appropriate risk level.
  • We maintain a regression test code coverage level of 80% or better at all times.
  • We follow strict code style and formatting guidelines (wiki/CodeStandards).
  • We process code comments with third-party tools to generate documentation.
