Steam Store description

SpaceSim is a particle-based simulation and rendering software, primarily focused on astrophysical applications. Important! This is a non-realtime simulator. Although low-resolution simulations are fast enough to be real-time, simulations with millions of particles can take several hours to finish. This is not a game . It does not contain any game mechanics, progression, sandbox elements, etc. Please do not expect any gaming experience. 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. You can recreate some of the well-known simulations from the scientific literature, such as the Moon-forming impact, the formation of the ring system of Saturn, or the DART kinetic impactor. Or you can simply explore various initial conditions, both grounded and realistic, but also hypothetical "what-if" scenarios, such as the collision of two planets made of matter and anti-matter. Fluid dynamics and gravitation 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 sim…
