About

Dr Llion Marc Evans holds an EPSRC Manufacturing Research Fellowship (2018-2023) at the Zienkiewicz Centre for Computational Engineering, College of Engineering, Swansea University. His main research interests are image-based modelling using the finite element method (IBFEM) and its application in high-value manufacturing (HVM).

Dr Evans completed his PhD at the School of Materials, University of Manchester in 2013. During which time he was part of the ‘Fusion Doctoral Training Network’ and awarded a CASE studentship by Culham Centre for Fusion Energy (CCFE). Since 2009 Dr Evans has worked on developing techniques for ‘Image-Based Finite Element Method’, a process which converts three-dimensional data (e.g. X-ray tomography) into high resolution simulations thus capturing features such as manufacturing defects. A major part of this work has been to adapt the ParaFEM simulation software for his work. This code is capable of handling FE meshes with hundreds of millions of elements by running over thousands of cores on supercomputers.

After his PhD Dr Evans worked at the UK Atomic Energy Authority (UKAEA) applying the IBFEM technique to investigate the manufacturing process for high heat flux components being designed for DEMO, the first demonstrational fusion power plant. He also used his background in X-ray tomography to contribute to the FP7 AMAZE project in additive manufacturing. He held the CCFE Fellowship (2013-2015), followed by a H2020 EUROfusion Researcher Grant (2015-2017).

Through the EPSRC Manufacturing Research Fellowship his work focusses on industrial application of IBFEM for Virtual Qualification. This research is in collaboration with Airbus Defence & Space, Diamond Light Source, Synopsys, TWI, UKAEA and University of Manchester.
