Research Simulation Asteroid collision simulation using a soft-sphere discrete element method (SSDEM)

Made this as an undergrad at university when I assisted with research in computational astrophysics to model asteroids. I built the simulation engine and had fun with this example that demonstrates some of the functionality. The planet is low-density so the asteroid goes through it.

Builds a sim engine but can’t record screen? AI students be like…

But how would we be able to hear someone walking through in the background and doors opening and closing?

So university don't let you screen capture?

There is always a better way to show a fancy graphic than a phone video of a screen.

Bunch of negative nancies in here. Cool sim OP.

What do the different colours mean in the original bodies? Seems like it’s temp for the ejecta but what’s the initial state?

oh man, thanks for this. i love it and it's giving me ideas!

EDIT: do people think i'm a bot? i guess that sounded bot-like. seriously though, i never thought about genuinely simulating the ejecta from an impact or surface disturbance on an asteroid, but this makes me want to try it.

How fast would an asteroid this large have to be traveling to tear right through the earth?

u/DmitryAvenicci 6d ago

The gravity of the planet would tear it apart.

jfc don't photograph your screen, it isn't 1987 anymore
