GitLab now enforces expiry dates on tokens that originally had no set expiration date. Those tokens were given an expiration date of one year later. Please review your personal access tokens, project access tokens, and group access tokens to ensure you are aware of upcoming expirations.

Kutalmış Berçin requested to merge feature-one-equation-turbulence-model into develop Oct 29, 2021

Summary

ENH: kL: new RANS model for geophysical applications
- STYLE: atmosphericModels: regroup atmospheric turbulence models
- ENH: kEpsilonLopesdaCosta: enable this RANS model for compressible applications
TUT: atmFlatTerrain: add an example for kL RANS model
- BUG: atmFlatTerrain: fix input settings in the plot script

Resolved bugs (If applicable)

A small issue in atmFlatTerrain/precursor/plot has been corrected.

Details of new models (If applicable)

For a given case, the kL model reduces numerical costs approximately by one-third in comparison to the kEpsilon model for geophysical applications.
A set of results obtained from the atmFlatTerrain and atmForestStability tutorials (left: kEpsilon, right: kL):

Risks

No changes in user input.
No changes are expected in output.
- The directory structure of src/atmosphericModels has been changed. Therefore, the location of the directory kEpsilonLopesdaCosta has also been changed. Might affect few minor things for a few developers. Not crucial, IMHO.

Tests

Compilation (incl. submodules):
- linux64ClangDPInt32Opt (clang11)
- linux64GccDPInt32Opt
- linux64GccSPDPInt64Debug
Alltest: No change in output with respect to the develop HEAD + no error
