This work presents a strategy to build reduced-order models suitable for aerodynamic shape optimisation, resulting in a multifidelity optimisation framework. A reduced-order model (ROM) based on a discrete empirical interpolation (DEIM) method is emp

Deep learning approaches have been shown to be capable of recognizing shape features (e.g. machining features) in Computer-Aided Design (CAD) models in certain circumstances, yet still have issues when the features intersect, and in exploiting the ge

Much literature exists on composite plate impact damage and residual strength post impact, but there is limited work which systematically examines how plate behaviour alters with plate aspect ratio and edge rotational restraint. Through simulation of

Generating fit-for-purpose CAE models from complex CAD assemblies is time consuming and error-prone. Tedious tasks include identifying and isolating the components of interest, removing duplicate components, and correcting inconsistent component inte

Design velocity measures the movement of the boundary of a CAD model as it undergoes a change in shape (e.g. due to the change in the value of a parameter). This paper combines and enhances two methods of calculating design velocity and uses the resu
