Today we are releasing our Stanford University Unstructured (SU2) open-source code. This is a collection of C++ based software tools for performing Partial Differential Equation (PDE) analysis and for solving PDE constrained optimization problems, with special emphasis on CFD and optimal shape design.

There are several important features of SU2 that distinguish it from other open-source CFD packages: - It is easy to implement new systems of governing equations (e.g. plasma, chemically reacting flows, etc.). - The architecture of the code separates the functionality of the different parts of the solver, allowing rapid implementation of new numerical schemes. - Lastly, SU2 incorporates everything needed to perform a complete design loop; from the ability to compute flow and adjoint solutions, to obtaining objective function sensitivities relative to specified design variables, and, using this information, drive gradient-based shape optimization through built-in mesh deformation algorithms.

SU2 is under active development in the Aerospace Design Lab (ADL) in the Department of Aeronautics and Astronautics at Stanford University and is released under an open-source license. More information can be found at: http://su2.stanford.edu
