Hello,
Purpose, make drag improvement with a topology module from OpenFOAM (exemple : external flow around a sphere).
I have been digging online and didn't find answer about this, is there someone who already modify the cost function in order to optimise drag?

All my research around AdjointShapeOptimization led me to those article quite old :

→https://www.tfd.chalmers.se/~hani/ku...ortAdjoint.pdf
→https://www.stce.rwth-aachen.de/files/ofw19_slides.pdf

I don't understand well these articles, where the cost function is coded and how to adapt all those parameters to my problem.
I would like to know if there are any recent updates that allow me to reach my purpose?

PS: I'm mainly searching solution without coding too much the source code of the adjoint method, which exceed my skills in C++ .

I hope this will help. Note that it is a different but more feature-rich solver. (adjointOptimisationFoam, not adjointShapeOptimizationFoam)
