SpaceSim - Astrophysical Simulation Software

SpaceSim is a particle-based simulation and rendering software, primarily focused on astrophysical applications. The goal of the project is to "de-mystify" scientific simulations and make them accessible to the general public. SpaceSim uses the same approach (albeit simplified and at lower resolution) as the research simulations typically run on supercomputers, but it can run on your desktop PC or laptop, comes with an intuitive user interface, and requires no extensive knowledge of mathematics, physics, or programming. Each deformable object in the simulation is discretized into particles that interact with each other through collisions (by solving the Navier-Stokes equations) and gravitational attraction. Objects can also be rigid (non-deformable) - they retain their shape, which simplifies collisions between objects and optimizes simulation speed.
