Su2 Foundation

What Su2 Foundation does

SU2 Foundation (legally Stichting SU2) is a Dutch nonprofit organization (ANBI-designated Public Benefit Foundation) headquartered in Delft, Netherlands, founded in 2019 to develop, maintain, and support open-source software for computational engineering sciences. Its core product, SU2 Code, is a C++ and Python-based suite for Partial Differential Equation (PDE) analysis and PDE-constrained optimization, covering computational fluid dynamics, aerodynamic shape optimization, heat transfer, fluid-structure interaction, and multidisciplinary design optimization. The codebase is freely distributed on GitHub (su2code) with documentation hosted on su2code.github.io, and is augmented by specialized modules including SU2-Turbo (turbomachinery), SU2-Nemo (hypersonics and non-equilibrium flows using Mutation++), and SU2-COOL (non-ideal compressible fluid dynamics).

The foundation operates as a community-governed, member-supported organization rather than a commercial vendor. Its executive board consists of 8 unpaid directors drawn from leading universities (TU Delft, Politecnico di Milano, Imperial College London, University of Twente) and industry (Bosch); revenue is generated entirely through a four-tier sponsorship program (Collaborator, Investigator, Innovator, Pioneer), conference registration fees (€500 for students/contributors, €1,000 for others; virtual participation free), and donations. The user community spans academic researchers, educators, and industry engineers in aerospace, automotive, energy, and manufacturing. Strategic partners include Bosch (Platinum sponsor), Cadence Design Systems, the National Institute of Aerospace, and several European and US universities; the foundation runs an annual conference series (2020–2026), developer meetings, and specialized training such as the Turbo Summer School.

Core offering

SU2 Foundation develops, maintains, and supports SU2, a collection of open-source C++ and Python-based software tools for Partial Differential Equation (PDE) analysis and PDE-constrained optimization. The core suite is used primarily for computational fluid dynamics (CFD), aerodynamic design, and multidisciplinary optimization, with specialized modules for turbomachinery (SU2-Turbo), hypersonic flows (SU2-Nemo), and non-ideal compressible fluid dynamics (SU2-COOL). All software is freely available on GitHub without licensing restrictions.

Product overview

The SU2 Foundation develops and maintains SU2, a collection of open-source C++ and Python-based software tools for Partial Differential Equation (PDE) analysis and PDE-constrained optimization. The core product, SU2 Code, serves as a multiphysics simulation and design optimization suite for computational fluid dynamics and aerodynamic applications. The portfolio includes specialized modules: SU2-Turbo provides turbomachinery-specific flow analysis and optimization capabilities, while SU2-Nemo addresses hypersonic and non-equilibrium flow problems using the Mutation++ thermochemistry library. SU2-COOL extends the platform for non-ideal compressible fluid dynamics. All tools are freely available and hosted on GitHub, with documentation and tutorials provided through the dedicated SU2 homepage.
