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.
