Here’s a fun interactive incompressible CFD simulation to gain some intuition for how fluids respond to local perturbations. I hope you gain some appreciation for the complexity of fluid dynamics but don’t forget to pause and awe at its endless beauty.
See what will happen when our Milky Way Galaxy inevitably collides with the Andromeda Galaxy if you don’t have the patience to wait 3.75 billion years! Here’s a fun N-Body particle simulation to do just that — be responsible!
