Hi Thor, This reads like a bug to me – would it be possible to provide a small dataset to reproduce this? Cheers, Corentin On 03/10/2024 01:47, Thor Tepper-Garcia via yt-users wrote:

Hi,

As other Ramses user probably know, sometimes particles can end up at the box boundaries, which effectively means they have left the simulation volume. I've noticed however that when reading in a Ramses snapshot, YT tends to keep the particles at the lower end of the boundaries (e.g. x =< 0 in c.u.), but removes all beyond the upper end (e.g. x >= 1. in c.u.). This may significantly bias the centre of mass when calculated using particles.

Thus my question is: How do I tell YT to either ignore or include all boundary particles when loading a snapshot?

Cheers
