Why use this?

SU2 is an open-source collection of software tools for solving partial-differential-equation analysis and PDE-constrained optimization problems on unstructured meshes. Its CFD solver handles direct, adjoint, and linearized solutions of the Euler, Navier-Stokes, and Reynolds-Averaged Navier-Stokes equations, with support for compressible and incompressible flow, heat transfer, and non-ideal gases.

Aerospace engineers choose SU2 when they need not only flow analysis but also gradient-based shape optimization, adjoint sensitivity analysis, and high-performance multiphysics simulation. It is widely applicable to aircraft, propulsion, automotive, marine, and renewable-energy problems, and its modular C++/Python architecture makes it suitable for research into new numerical methods and design workflows.
