The aeroelastic effects are almost negligible at low speed, where the maximum downforce is sought to increase the speed in the bends. Thus, structural strain at high speed may be accomplished to increase the top speed on a straight trajectory.

This project is focused on applying a robust optimization method in the design of a real part. The work consisted of analyzing the aerodynamic and structural effects applied to a rear wing of a Formula-type vehicle. In order to accomplish this goal it is necessary to optimize bearing in mind of both disciplines and employing new coupling capacities featured in the software, as well as the versatile control and advanced statistical tools provided by modeFRONTIER.

The whole optimization cycle is controlled and managed by a workflow generated in the modeFRONTIER 4.2 environment. This system is comprised of all software components required, such as the necessary automation logic to use the calculations according to a weak coupling without running the software programmes simultaneously for every step of the process. The figure below shows the simplified description of the combined MEF and CFD calculation. The software programmes share the data resulting from each iterative simulation, as many times as necessary to achieve the tolerance required by the designer.
