SIMDAT: Overview of Aerospace Scenario 1.A Design Service to generate the DoE 2.A Geometry Service to produce instances of the wing’s geometry 3.An Aerodynamics service in order to compute the air flow over the geometry under consideration and output noise sources as well as forces of interest (e.g. lift, drag) 4.An Acoustics Service that takes the noise sources produces from the aerodynamics service and propagates the noise Optimise the positioning of wing’s high lift device. The current work has focused on running a candidate set of designs from a Design of Experiments (DoE). The scenario involves:
