Description: | |
Computational Fluid Dynamics (CFD) is a key element of modern engineering R&D and of digital engineering processes in Industry4.0. In a CFD code, the fundamental equations of fluid flow are discretised and solved numerically; this process of discretisation involves splitting the domain of interest into subdomains called cells, which make up the mesh covering the domain. The process of creating this mesh, referred to as meshing, is one of the most critical steps in the CFD workflow, as the quality of the numerical solution (and sometimes even the ability of the CFD code to find a solution) can be very strongly dependent on the quality of the mesh. At the same time, the meshing process itself is complex and often involves considerable human time and expertise to accomplish. Automated meshing programmes (such as snappyHexMesh, sHM, from the OpenFOAM suite of CFD codes) have been developed, but these simply automate the construction of the mesh from a large number of input parameters; finding the correct inputs is still complex and (human-)time consuming. New developments in AI technologies present the potential to revolutionise the meshing process however. AI technologies such as Artificial Neural Networks (ANNs) are good at discovering and reproducing human expertise, and could be used to “learn” what makes a good mesh. Machine Learning (ML, a branch of AI) can be used to iteratively improve mesh quality, based on commonly used (and easy to evaluate) mesh quality metrics – essentially automating and improving on the typical ad hoc meshing and re-meshing cycle used by human CFD engineers. Finally, automated mesh generators such as sHM use text-based input files that can be reproduced by Large Language Models (LLMs) such as ChatGPT. This presents a completely new and disruptive methodology to create the input files for CFD simulation, using carefully honed query terms and re-trained LLMs. The aim of the proposed PhD project is to investigate all these aspects of AI applied to meshing, which represents a truly disruptive technology for this important engineering tool. The application process has two stages; supervisors nominate one candidate to go forward to a panel interview which will award funding to 4 of the 8 QuEX projects being advertised.
