WP 6: Adjoint-based Optimisation Workflows

Objectives

• Improved accuracy geometry representation for changing topologies
• Smart multi-objective trade-off selection
• Productivity enhancing automated workflow

Methodology

A combined level-set/immersed boundary framework will be implemented at ENGS to more accurately represent solid-fluid interfaces. The adjoint solver framework will be extended to incorporate multiple primal solution points. Algorithms for design for a constrained objective in a multi-objective scenario through low fidelity modelling will be developed. A workflow framework that ties all the component elements together will be created. A range of parametrisation methods will be implemented in the RR and VW design chains, with particular focus on CAD-based or CAD-return methods.
