SpaceSim
A new graphical application that uses the OpenSPH solver, but with a user interface that is more interactive, intuitive, and easy to use. This version is still under development.
If you have any questions, ideas for what to change, or you notice a bug, come chat on the Discord server. You can support the development by becoming a Patron.

OpenSPH
OpenSPH is a library and graphical application used primarily for scientific simulations. Simulations are set up using a node-based editor that allows you to customize initial conditions and individual simulation steps.
