SU2: An open-source suite for multiphysics simulation and design

Abstract

This paper presents the main objectives and a description of the SU2 suite, including the novel software architecture and open-source software engineering strategy. SU2 is a computational analysis and design package that has been developed to solve multiphysics analysis and optimization tasks using unstructured mesh topologies. Its unique architecture iswell suited for extensibility to treat partial-differential-equation-based problems not initially envisioned. The common framework adopted enables the rapid implementation of newphysics packages that can be tightly coupled to form a powerful ensemble of analysis tools to address complex problems facing many engineering communities. The framework is demonstrated on a number, solving both the flow and adjoint systems of equations to provide a highfidelity predictive capability and sensitivity information that can be used for optimal shape design using a gradientbased framework, goal-oriented adaptive mesh refinement, or uncertainty quantification.
