A flow solver based on Smoothed Particle Hydrodynamics, in which the fluid is represented as a set of particles rather than a mesh. It runs on multi-core CPUs and on NVIDIA cards with CUDA, which makes millions of particles feasible in reasonable time. Coastal and hydraulic engineers use it to study wave impact on breakwaters and jetties, overtopping of embankments, sloshing in tanks and flow through control structures, where classic mesh-based methods struggle. The package ships with processing tools and ready examples. It takes time to learn, and a strong graphics card makes a big difference.
