OpenBF is an open-source 1D blood flow solver based on MUSCL finite-volume numerical scheme, written in Julia and released under Apache 2.0 free software license. The software is developed by Alessandro Melis and Alberto Marzo at the Insigneo Institute at the university of Sheffield (UK). The solution is currently exposed as open source software; it is also installed on SURFsara’s HPC-Cloud, where it is used for large-scale sensitivity analysis and uncertainty quantification studies.
