This repository contains a GPU-accelerated version of the HemeLB lattice Boltzmann code for large scale fluid flow in complex geometries.

The initial version of the CUDA kernel was implemented by Benjamin T. Shealy, Ashwin T. Srinath, and Ulf D. Schiller during the OLCF GPU Hackathon 2018. Mehrdad Yousefi helped setting up test geometries for benchmarks.
