Airfoil optimization using Design-by-Morphing [PDF]

open access: yesJournal of Computational Design and Engineering, 2023
Abstract Design-by-Morphing (DbM) is a novel design methodology that creates a search space for topology optimization. Traditional design techniques often impose geometric constraints and, sometimes, the designer’s biases on the design space, which restricts the novelty of the designs and allows for only small local changes.
