'''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. Aranake, A. Campos, S. R. Copeland, T. D. Economon, A. K. Lonkar, T. W. Lukaczyk, T. W. R. Taylor, and J. J. Alonso, "Stanford University Unstructured (SU2): An open-source integrated computational environment for multi-physics simulation and design", AIAA Paper 2013-0287, 51st AIAA Aerospace Sciences Meeting and Exhibit. January 7th -– 10th, 2013. Grapevine, Texas, USA.]</ref> but has been extended to treat more general equations such as [[electrodynamics]] and chemically reacting flows. SU2 supports continuous and discrete adjoint for calculating the sensitivities/gradients of a scalar field.

SU2 v7.1.0 aims to consolidate the new features added in versions 7.0.X.

Those include new solvers, performance upgrades, new output formats, more multiphysics capabilities, tweaks/fixes/updates to models and schemes used less often, and an effort to restructure the code to make it more accessible to new developers. Some options that became redundant in v7.0.0 were removed which may result in errors for older configuration files, the error messages should point the solution to these problems.

| {{dts|format=dmy|2021|8|17}}

| SU2 version 7.2.0 introduces exciting new features and improvements (it differs from 7.1.1 by almost 1000 commits!) We made a pause from the monthly maintenance-release cycle to integrate those features as best as possible, they include:

* Unsteady discrete adjoints for multizone problems (e.g. FSI and CHT).

* Hybrid parallelization (MPI + OpenMP) of discrete adjoint solvers.

* New boundary conditions and important corrections to RANS wall functions and transition models.

* Usability improvements, such as speeding up the NEMO preprocessing for large problems, restarting from results on non-matching grids, suggestions for incorrect config options, etc.

* Numerous fixes based on feedback from the SU2 community.

As with 7.1.0, we used this version to deprecate some more options leftover from 7.0.0, and to revise others in preparation for new features to come.
