Visions of Exascale CFD: ASME Fluids Engineering Division Summer Meeting

Visions of Exascale CFD

Over the past thirty years, computational simulation of fluid dynamics has made huge strides in meshing of complex geometries, computational efficiency and most importantly, greater fidelity in physics models.Current trends include greater adoption of unsteady methods via LES, higher order methods and alternatives to classical CFD such as Lattice Boltzmann methods.However, the majority of engineering applications remain constrained by computational and storage resources as well as schedule and time pressure.The Department of Energy’s Exascale Computing Project (ECP) offers the capacity for scale, fidelity and perhaps most interesting, non-deterministic engineering (NDE) in which variations in boundary conditions, discretization and models can more realistically predict the behavior of complex aerodynamic, propulsion or power generation systems.

Intelligent Light is participating in research activities aimed at managing the massive data flows resulting from ensembles of unsteady CFD calculations and implementing tools to support engineering use of uncertainty quantification techniques.Through the lens of post-processing and data analysis, we have gained a unique perspective on research and engineering use of CFD from the late 1980’s through today.The talk will touch on this history but have a primary focus on state-of-the-art petascale CFD in aerospace, combustion and wind energy and survey the challenges that ECP is intended to address.
