What is OpenSPH?

OpenSPH is a library and a GUI application for hydrodynamic and N-body simulations. It uses SPH discretization in space and currently is specialized for simulations of asteroid impacts. The code is being developed on Astronomical Institute of Charles University. It aims to provide a fast, versatile and easily extensible SPH solver utilizing modern CPU features (SSE/AVX instruction sets).
