SU2 (software)

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

The most active groups developing SU2 are:

• Prof. Juan J. Alonso's group at Stanford University.
• Prof. Piero Colonna's group at Delft University of Technology.
• Prof. Nicolas R. Gauger's group at Kaiserslautern University of Technology.
• Prof. Alberto Guardone's group at Polytechnic University of Milan.
• Prof. Rafael Palacios' group at Imperial College London.

SU2 is a general-purpose multiphysics suite designed for the simulation of partial differential equations (PDE) on unstructured meshes. The framework is built to handle complex multi-physics interactions through a multi-zone approach, allowing different physical models to be solved in connected domains. Its current capabilities include:

• Flow Regimes: Compressible and incompressible solvers for Euler, Navier-Stokes, and RANS equations across all Mach regimes (low-speed to hypersonic). For low Mach incompressible flow problems, preconditioning methods are used.
• Turbulence & Transition Modeling:
  • RANS Models: Includes several variants of the Spalart-Allmaras (SA) and Menter's Shear Stress Transport (SST) models, including curvature and rotation corrections (QCR).. The turbulence models include classical wall functions.
  • Scale-Resolving Methods: Support for Large eddy simulation (LES), Detached eddy simulation (DES), and Delayed Detached Eddy Simulation (DDES) for unsteady separated flows.
