The following is an aerodynamic shape optimization case for the NREL6 wind turbine blades.
Case: Wind turbine aerodynamic optimization Geometry: NREL6 Objective function: Torque Design variables: 100 FFD points moving in the x and y directions Constraints: None Inlet velocity: 7 m/s Rotation speed: 7.5 rad/s Mesh cells: 800 K Solver: DATurboFoam

To run this case, first download tutorials and untar it. Then go to tutorials-master/NREL6_Wind_Turbine and run the “preProcessing.sh” script to generate the mesh:
We recommend running this case on an HPC system with 80 CPU cores:
mpirun -np 80 python runScript.py 2>&1 | tee logOpt.txt
