HiPIMS standards for High-Performance Integrated hydrodynamic Modelling System. It uses state-of-art numerical schemes (Godunov-type finite volume) to solve the 2D shallow water equations for flood simulations. To support high-resolution flood simulations, HiPIMS is implemented on multiple GPUs (Graphics Processing Unit) using CUDA/C++ languages to achieve high-performance computing. Since HiPIMS has a modular and flexible structure, it has a great potential to be further developed for other applications in hydrological science as long as the problem can be solved on a uniform rectangular grid.
HiPIMS has been embedded in Pypims, the Python APIs for hipims, which provides a user-friendly and powerful interface for data pre-processing, running hipims and result visualisation.
HiPIMS is maintained by the Hydro-Environmental Modelling Labarotory, a research hub for technological innovation and interdisciplinary collaboration. We warmly welcome the hydro-environmental modelling community to contribute to the project, believing that this project will benefit the whole community.
