Particles in Athena++ ?

[wadsley]

I have been using old Athena (C) to simulate dust in shearing boxes. I would like to take advantage of the adaptivity in Athena++ and do similar things. I would be willing to code a bit if needed but I'd prefer to start from an existing particle type in the code. To be specific, I'd like to do dust in shearing boxes with self-gravity. The documentation does not mention particles but I thought there might be some experimental work or a bit of a basic framework for particles already in existence somewhere.

Dear Dr. Wadsley,

There are two versions of dust particles in development. I am developing the Lagrangian type, while Pinghui Huang & Xuening Bai (2022) are developing the Eulerian fluid type. However, the Lagrangian dust particles are not ready for shearing box yet; on the other hand, the fluid dust should be available for shearing box.
More seriously, self-gravity in shearing box also needs quite some attention in development. Kazunari Iwasaki and @tomidakn may have more information on this front.

Sincerely,
Chao-Chin
