OpenSPH

Versatile particle code for astrophysical simulations

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.
