Changes

The highlights of SU2 version 8.0.0 are:

  • A complete re-work of the Python wrapper to allow in-memory mesh deformation, increased flexibility to access the solution for post-processing or initialization, and also to manipulate boundary conditions during the solution (see examples)
  • Modeling of combustion #1917
  • Improved performance for hybrid parallel discrete adjoint solvers
  • Data-driven fluid models
  • Improved consistency of the SST implementation with literature, with SST-2003m becoming the new default

SU2 version 7.4.0 introduces important new features and fixes:

  • SST-2003m and some of its variants.
  • New way of specifying and combining SA variants and corrections
  • Fixes of hybrid parallel race conditions (for primal and discrete adjoint modes).
  • User defined output functions (example).
  • Many other improvements and fixes listed below.

NOTE: This release breaks backward compatibility for less common SA models, in favour of the new, and more versatile, way of specifying SA and SST versions and corrections.

🚀 Experimental Features

  • Build SU2 and run regressions on self hosted aarch64 runner scheduled @martin-g (#1619)
  • Use latest build-su2-cross Docker image for release-management Github Actions workflow @martin-g (#1693)
  • Composition-dependent density model for variable density incompressible flow @Cristopher-Morales (#1620)
  • New SA version/correction combinations and new way of specifying them in the config (SA_OPTIONS=...) @pcarruscag (#1646)
  • Newton-Raphson for NEMO temperature computations @WallyMaier (#1627)
  • Refactor SST model implementation and addition of variants/corrections @bigfooted @WallyMaier (#1560)
  • Improve cauchy convergence to handle quantities that converge to small values @ArneVoss (#1577)
  • Free-flying aircraft that translates and rotates about the center of gravity (rotating frame + translation) @ArneVoss (#1621)

💊 Bug Fixes

  • Correct type of history field for INVERSE_DESIGN_PRESSURE and update history map @pcarruscag (#1730)
  • Fix #1667 Potential crash for the OpenMP multi-thread running. @lcheng9 (#1678)
  • Hybrid Parallel (AD): Fix Race Conditions @jblueh (#1679)
  • Fix missing phase angle in calculation of grid velocity for rigid pitching motion @HL-ZHI (#1656)
  • INCINLET_USENORMALS uses normal of inlet boundary for velocity inlets in addition to pressure inlets @bigfooted (#1643)
  • Bugfix for a call to LoadUnsteady_Solution in CDiscAdjFluidIteration::Preprocess @MaxSagebaum (#1638)
  • Fix incompressible velocity inlet on intersections with viscous walls @bigfooted (#1631)
  • Solve segmentation faults for FULLMG_CYCLE @suargi (#1362)
  • Fixes #1568 - Prefer loading zlib and szip libraries dynamically @martin-g (#1632)

SU2 version 7.3.0 introduces important new features:

  • Passive species transport (tutorial).
  • A smoothing method for discrete adjoint gradients (example).
  • Customizable objective function (example).
  • Options to keep intermediate solution files (documentation).
  • Robustness improvements of the NEMO solver.
  • HDF5 backend for CGNS meshes.

This release includes an important fix to the SA-neg turbulence model which could reduce oscillations in the solution, the option CONV_CRITERIA had been marked for deprecation in v7.2.1 and it is now removed.

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.
