Block-structured compressible Navier–Stokes solution using the OPS high-level abstraction

abstract In this paper, we report the development and validation of a compressible solver with shock capturing, using a domain-specific high-level abstraction framework, OPS, that is being developed at the University of Oxford. OPS uses an active library approach for block-structured meshes, capable of generating codes for a variety of parallel implementations with different parallelisation strategies. Performance results on various architectures are reported for the 1D Shu–Osher test case.

Solution field data from a three-dimensional Taylor-Green vortex simulation

Solution field data from a three-dimensional Taylor-Green vortex simulation, performed using the OpenSBLI code with a uniform grid of 256^3 points.

Enstrophy and kinetic energy data from 3D Taylor-Green vortex simulations

Enstrophy and kinetic energy data from four 3D Taylor-Green vortex simulations, using uniform grids of 64^3, 128^3, 256^3, and 512^3 solution points. The simulations were performed using the OpenSBLI code developed at the University of Southampton.Dataset to support: Jammy, Satya, Jacobs, Christian and Sandham, Neil (2016) Performance evaluation of explicit finite difference algorithms with varying amounts of computational and memory intensity.
