Propeller blade performance

[Charly-28]

I would like to optimize the shape of the propeller blade.

1. My first objective function will be the aerodynamic performance (the ratio of thrust on the torque). How is this function integrated in daFoam?

We have thrust and torque but do not have their ratio as the objective function yet, you have to implement it.

Thanks for your reply.
Where should I implement the objective function?
What are the steps to follow?

You need to add a child class to DAObjFunc. Refer to src/adjoint/DAObjFunc/DAObjFunForce.C for reference.
