SU2 v7 Blackbird

Powerful. Fast. Free.



What is SU2?

Computational analysis tools have revolutionized the way we design engineering systems, but most established codes are proprietary, unavailable, or prohibitively expensive for many users. The SU2 team is changing this, making multiphysics analysis and design optimization software freely available and involving everyone in its creation and development.

Find a detailed description of the code philosophy, components, and implementations in the SU2 AIAA Journal article. Whether it's discrete adjoints, non-ideal compressible CFD, high-performance computing, or incompressible flows with heat transfer, SU2 has something for you.

A strong foundation.

The SU2 community continues to grow rapidly, and together, we are making a measurable, worldwide impact on CFD. Now, it's time to tap into our collective expertise, creativity, and skills to take the project to the next level.

We are proud to announce the SU2 Foundation, a new non-profit organization formed in the United States. The mission of the SU2 Foundation is to promote global software development and education to increase the pace of innovation in the engineering sciences for the benefit of all society.

Meet state-of-the-art.

SU2 isn't just software. It's a scientific research platform. Catch up to the state-of-the-art and push the boundaries in your field with SU2.

SU2 is an open-source collection of software tools written in C++ and Python for the analysis of partial differential equations (PDEs) and PDE-constrained optimization problems on unstructured meshes with state-of-the-art numerical methods. Through the initiative of users and developers around the world, SU2 is now a well established tool with wide applicability to aeronautical, automotive, ship, and renewable energy industries, to name a few.
