In this video, we apply aerodynamic shape optimization using the adjoint technique to the Ahmed Body. This famous geometry was used to benchmark CFD codes, correlate to wind tunnel test data and so on for automotive related aerodynamics projects.

The method runs through a number of cycles, each containing:
a primal run (normal CFD simulation of the aerodynamics)
a dual run (adjoint simulation to link the drag reduction goal to the flow field)
a sensitivity map calculation (to calculate how the surface should be morphed to reduce drag)
a morphing step to implement these suggestions. The morphing is applied to the volume & surface mesh directly
