🚨Join @hannorein & the rest of us for the first (not 24th!) 2-day virtual REBOUND meeting, aimed to bring REBOUND developers and users together. 1 day of science talks, 1 day of technical/hands-on talks, discussions on REBOUND's future + social events! 🔭

oh god, what a nightmare

We also renamed the master branch 'main'. If you run into any problems running the code, the easiest fix is just to pip uninstall rebound and reboundx, and pip install them again. Open an issue on github if you run any issues!

6/6

If you cloned the repo and have a local REBOUNDx folder, you will no longer be able to merge new changes to REBOUNDx, and won't be able to contribute code to the repo. Just rename your reboundx dir (as a backup for files you've edited) and git clone again.

5/6

Over time, REBOUNDx accumulated several large unused files in its git history, which made the repo over 100 MB. I have now removed them, making it 13MB, and hope to avoid further large files.

If you just ran pip install reboundx to use the package, no action is needed.

4/6

Many effects you might want to use for planetary dynamics are already implemented: tides, GR, migration, radiation pressure, J2 etc. A full list can be found here:

reboundx.readthedocs.io/en/latest/ef...

REBOUNDx also makes it easy to attach parameters to particles in your integrations.

3/6

REBOUND is an N-body package w/ great integrators for point-source gravity. Rather than add effects like tides etc directly to REBOUND, Hanno & I decided to write a separate library REBOUNDx to hold implementations of common effects & make it easy for others to contribute.

2/6

🚨 REBOUNDx users: 🔭

TLDR: If you used pip install reboundx, everything still works. If you cloned the reboundx repo, you need to delete and clone it again.

If you use the REBOUND N-body package but wished you could add tides, post-Newtonian corrections etc, this 🧵 is also for you

In case anyone else out there is as incompetent as me, I wasn't sure how I would connect with astrotwitter on here, but it turns out I just had to scroll through @aussiastronomer.bsky.social and @duetosymmetry.com 's follows to find everyone I followed on Twitter 😅
