libWallModelledLES is a library based on OpenFOAM® technology, extending the capabilities of OpenFOAM in the area of wall-modelled LES (WMLES). This is a turbulence modelling methodology, which allows to make LES cheaper by not resolving the inner region of turbulent boundary layers.

If you use the library, please cite the following publication. This is also a good source for understanding the theory behind the models.

See "Installation" section on the documentation portal. In short: the latest ESI versions should work, Foundation version 7 and below should work.

Please first read the troubleshooting section in the documentation. If that does not help, please open an issue on Github!

This code is available on several public repositories:

• Github --- the main repository, where all the development happens, and where you should open issues to get help.

• Bitbucket --- mirror, which only gets update upon new releases.

• Gitlab --- mirror, which only gets updated upon new releases.

If your works is missing from this glorious list and you want it here, open an issue!
