Abstract

This paper presents the application of the continuous adjoint method, programmed in OpenFOAM\(^{\copyright }\), combined with an RBF-based morpher to the aerodynamic optimization of a generic car model. The continuous adjoint method produces accurate sensitivities by utilizing the full differentiation of the Spalart–Allmaras turbulence model, based on wall functions, while the RBF-based morpher provides a fast and versatile way to deform both the surface of the car and the interior mesh nodes. The integrated software is used to minimize the drag force exerted on the surface of the DrivAer car model.
