Dr. Gihan Mudalige has been awarded a 4-year, Royal Society Industry Fellowship to work with Rolls Royce plc., on their turbomachinery design simulation applications from September 2018.

Companies such as Rolls-Royce, crucially depend on High Performance Computing (HPC) based numerical simulation applications for the design of turbomachinery. These complex multi-physics and engineering applications, predominantly based on computational fluid dynamics (CFD), even in their simplest form, provide insights into aspects of aircraft engines which could not otherwise be achieved in the absence of physical testing. Developing such simulation applications is difficult and expensive, taking years to write, test and verify. They can easily contain millions of lines of code. Consequently, such programs have lifetimes of decades compared to the supercomputers that run them, which advances every 2-4 years. In the next five years, HPC systems are expected to reach thousand times the capabilities of current systems, attaining exascale (10¹⁸) performance where a single system can perform million-trillion computations every second. The range of processor architectures, networks, memory, their configurations and scale make it difficult to know what type of systems will dominate exascale machines and how best to programme them to gain optimal performance. Poor performance means less simulation for your money or worse, a completely inoperable suite of codes. Such an outcome will mean a significant loss of investment. The underlying objective of this fellowship project is to re-design Rolls-Royce’s simulation codes to meet these challenges. This work will utilize the OP2, high-level embedded Domain Specific Language developed by Dr. Mudalige and his research collaborators at University of Oxford, PPCU Hungary and Imperial College London, aiming to re-engineer Rolls-Royce’s CFD applications suite and deploy it for production simulations.
