SU2 version 3.2 now available!

by SU2 development team

The SU2 team is excited to announce the version 3.2 release of the SU2 open-source code (http://su2.stanford.edu). SU2 is a collection of C++ software tools for performing Partial Differential Equation (PDE) analysis and for solving PDE-constrained optimization problems, with special emphasis on Computational Fluid Dynamics (CFD) and aerodynamic shape design.

This update to the SU2 suite features major improvements to the performance, robustness, and usability of the code. The infrastructure for parallel calculations has been completely revamped, including more efficient mesh partitioning. Stricter configuration file parsing helps keep your simulation parameters organized and error-free. A unified suite of test cases, now available directly from GitHub, makes getting up and running with SU2 easier than ever

Version 3.2 contains the following notable updates:

  • Renamed C++ modules for clarity:
    • SU2_DDC ---> SU2_PRT
    • SU2_MDC ---> SU2_DEF
    • SU2_MAC ---> SU2_MSH
    • SU2_GDC ---> SU2_GEO
    • SU2_GPC ---> SU2_DOT
  • Stricter checking and improved error messages for robust parsing of configuration options.
  • Unified set of SU2 test cases (meshes and config. files) are now available on GitHub (https://github.com/su2code/TestCases).
  • Major updates to the MPI implementation that improve performance and align with the MPI 3.0 standard.
  • Modifications that greatly enhance computational efficiency and memory scalability of mesh partitioning for parallel calculations.
  • New constant lift mode. Specify a target lift coefficient rather than a fixed angle of attack.
  • Upgrades to the CGNS mesh reader for further support of mixed-element meshes.
  • General bug fixes and maintenance.

SU2 Version 3.2.0 is available today for download from the SU2 download page.

As always, we would like to thank the open-source community for their interest, help, and support.
