Super-computers are about to change the virtual world in which computational fluid dynamics exists. James Hawkes (Phd of University of Southampton and Marin Academy) goes exploring and describes the changes that will revolutionise vessel design in his article at the Naval Architect, issue of July/August 2015.
Here an excerpt related with his ReFRESCO work: “… Work is currently being undertaken at the University of Southampton, in conjunction with the Maritime Institute Netherlands (MARIN) to improve the scalability of the core algorithms. Particularly this focuses on scaling the linear solvers to a many-core environment and investigating dynamic balancing for dark silicon. Other developments for scalable CFD tackle such areas as:
- Parallel methods for grid generation: ensuring that reading or creating mesh data does not become a bottleneck to the solver.
- Scalable post-processing: using Big Data analytics to create useful results from millions of cells in a computationally efficient way.
- Scalable discretisation techniques: especially concerning sliding or overset mesh technology.
- Parallel time-stepping: allowing the time domain to be parallelised, improving scalability by partitioning the simulation in four dimensions.
New thinking is required in the development of CFD to obtain a harmony between hardware, software and hydrodynamics. Whether the codes are commercial, open-source or in-house; utilising super-computers or desktop workstations; for one-off high-resolution simulations or batch optimisation – they must adapt to stay ahead of the game. …”
