USING TRACE VS MERCURIUS

[byrdeloor9]

Hello, I'm currently using rebound for my Tesis of my Master's Degree, and i'm currently using MERCURIUS as a Integrador in C to simulate a fragmentation model for the collisions, i saw that there is a new version called TRACE that is an improvement on MERCURIUS available on Python, so i tried to use it in my project, but i get this message in the console when using it:

Error! TRACE does not support adding particles mid-timestep

So my question is if TRACE can be used to simulate fragmentation problems? and if so? how would it be possible to do so?
Thank u so much for ur time, and thank u in advance for your response.

Best Regards,

Hi Byron,

The message is correct. Right now TRACE does not support adding particles during a timestep. So if your fragmentation algorithm produces particles during collisions, then it will not work with TRACE. This is a feature that could in principle be added, there just hasn't been a need for it yet. @tigerchenlu98, do you have a feeling for how complicated it would be to do this?

Hi all,

Sorry for the late response, the holidays have been rather hectic. @hannorein, I don't think this should be very difficult -- we'd just have to make every step in which particles are added an irreversible step a la collisions. I can take a stab at it this week.
