Corrected actuator line models in OpenFOAM

During the development of the Verification, Validation and Uncertainty Quantification (VVUQ) framework by the HPCWE project partner University of Stuttgart, code errors have been found and corrected in the actuator line model of the turbinesFoam library, that works as an add-in to the OpenFOAM software. The error corrections in the code were published under a GNU General Public License v3.0 on Github. Read more about the specific corrections here.
