SU2 is a suite of open-source software tools written in C++ for the numerical solution of partial differential equations (PDE) and performing PDE constrained optimization. The primary applications are computational fluid dynamics and aerodynamic shape optimization,[1] but has been extended to treat more general equations such as electrodynamics and chemically reacting flows.

SU2 is being developed by individuals and organized teams around the world. The SU2 Lead Developers are: Dr. Francisco Palacios and Dr. Thomas D. Economon.

The most active groups developing SU2 are:


The SU2 tools suite solution suite includes[2]

  • High-fidelity analysis and adjoint-based design using unstructured mesh technology.
  • Compressible and incompressible Euler, Navier-Stokes, and RANS solvers.
  • Additional PDE solvers for electrodynamics, linear elasticity, heat equation, wave equation and thermochemical non-equilibrium.
  • Convergence acceleration (multi-grid, preconditioning, etc.).
  • Sensitivity information via the continuous adjoint methodology[3] approach.
  • Adaptive, goal-oriented mesh refinement and deformation.
  • Modularized [4] C++ object-oriented design.
  • Parallelization with MPI.
  • Python scripts for automation.


SU2 is free and open source software, released under the GNU General Public License version 3 (SU2 v1.0 and v2.0) and GNU Lesser General Public License version 2.1 (SU2 v2.0.7 and later versions).[5]
