Gerris Flow Solver
Website
Gerris Flow Solver is a very different software project but one in use around the world by scientists and engineers working in the field of fluid dynamics. It stands out in this field as an open source offering amongst a number of strong commercial packages, providing anyone with the curiosity and enthusiasm to explore fluid behaviours with a rich toolset. Its modular design means Gerris will continue to expand with a growing community of developers continuing to improve the core product. Gerris is the work of Stephanie Popinet of NIWA in Wellington and it attracted a significant number of nominations in recent New Zealand Open Source Awards from grateful and enthusiastic users both here and overseas.
