Automated development of novel finite-element formulations

About the Project

The Finite Element Method (FEM) is widely used for numerical simulation in Engineering, for example in modelling deformable solids. While significant advances have been made in many aspects of the method, most FEM implementations rely on standard polynomial interpolations and Gaussian numerical integration. Recent results in numerical integration for higher order polynomial FEM interpolations show that significant improvements in computational efficiency can be obtained by developing customised formulations. The effort involved in developing such customised formulations, however, currently limits the applicability of this approach. This PhD project will focus on developing an automated framework for developing, testing, and selecting non-standard interpolation and integration methods leading to highly efficient FEM formulations, adapted to the characteristics of the input problem. Established heuristic optimisation approaches will be complemented by novel AI/agentic techniques to locate optimal formulations across a wide search space. The research in this project will be based on existing preliminary work and proof-of-concept tools using both computer algebra software for symbolic calculations (Maple) and numerical computation software (Matlab, Python or Julia). Specific new results obtained through the automated framework will be implemented and tested within commercial computational mechanics codes, such as the Abaqus FEM software.

Minimum entry qualification - an Honours degree at 2:1 or above (or International equivalent) in a relevant science or engineering discipline, possibly supported by an MSc Degree. Applicants must demonstrate an appropriate background in numerical analysis, programming, mechanics of materials and/or computational mathematics.
