OpenSPH is described as 'C++ SPH/N-body library and standalone GUI application, mainly designed for astrophysical simulations' and is an app in the education & reference category. There are six alternatives to OpenSPH for a variety of platforms, including Windows, Steam, itch.io, Linux and Android apps. The best OpenSPH alternative is Universe Sandbox. It's not free, so if you're looking for a free alternative, you could try Galaxy Engine or Space Crash Simulator. Other great apps like OpenSPH are Space Simulation Toolkit, SpaceSim and Milky Way.
Create & destroy on an unimaginable scale with a realistic physics-based space simulator. Explore the beauty of our universe and the fragility of our planet. Use science to bend the laws of gravity, collide planets, boil away oceans, fire epic space lasers, and customize your universe.
Simulate the physics of the Universe on a large scale and create stunning visuals. Play with intergalactic interactions, smash planets together and even create the Big Bang itself!.
Physics sandbox game that uses a graphics card as a supercomputer. Change the laws of physics, design mechanisms, create A-Life worlds and inhabit them with living beings.
Real-time planetary collision sandbox powered by SPH physics: smash planets together and watch the destruction and its aftermath!.
Simulation & rendering software that uses Smoothed Particle Hydrodynamics (SPH) to simulate collisions of celestial bodies, accretion disks around black holes, or formation of galaxies in the early universe.
If you're a fan of Solar Smash, Universe Sandbox, Spaceflight Simulator, Solar System Sim; this is your new favorite game!
