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
