Decoupling of Control and Force Objective in Adjoint-Based Fluid Dynamic Shape Optimization
Niklas Kühl, Peter M. Müller, Arthur Stück +2
We discuss exterior and classical interior alternatives for evaluating fluid flow induced forces on bodies. The discussion aims at a reduction of the total shape derivative, achiev…
