'''SU2''' (formerly '''Stanford University Unstructured''') is a suite of [[Open-source software|open-source]] software tools written in C++ for the numerical solution of [[partial differential equation]]s (PDE) and performing [[PDE-constrained optimization]]. The primary applications are [[computational fluid dynamics]] and aerodynamic [[shape optimization]],<ref>[http://su2.stanford.edu/documents/SU2_AIAA_ASM2013.pdf F. Palacios, M. R. Colonno, A. C.

SU2 supports continuous and discrete adjoint for calculating the sensitivities/gradients of a scalar field.

==Capabilities==

Line 267 ⟶ 266:

* New in-memory Python wrapping of SU2 using SWIG with accompanying high-level API.

* Class enhancements for multiphysics applications, including interpolation and transfer.

* Free-form deformation (FFD) extensions, including bezier[[Bézier curvescurve]]s and improved usability.

* Reorganization of the incompressible solver for future expansion.

* Harmonic Balance flow analysis capability.
