Description A new Open source code has been developed and released. OpenSBLI is a Python-based modelling framework that is capable of expanding a set of differential equations written in Einstein notation, and automatically generating C code that performs the finite difference approximation to obtain a solution. This C code is then targeted with the OPS library towards specific hardware backends, such as MPI/OpenMP for execution on CPUs, and CUDA/OpenCL for execution on GPUs. The main focus of OpenSBLI is on the solution of the compressible Navier-Stokes equations with application to shock-boundary layer interactions (SBLI). However, in principle, any set of equations that can be written in Einstein notation may be solved.
Exploitation Route Open source code can be applied to other application areas where finite difference solutions of ordinary and partial differential equations are desired.
The OpenSBLI code is now suitable for applications in high speed aerodynamics, see for example https://eprints.soton.ac.uk/445538/

Description Software developed has enabled us to assess the energy-efficiency of numerical algorithms. The open source software OpenSBLI has been released. version 2 has now been released (2019) We have also used the software for advanced undergraduate teaching (modules SESA6061 and SESA6082), enabling 100 student to date to have exposure to a research computer code. A benchmark version of the OpenSBLI code has been used during procurement of the Archer 2 national supercomputer.
