[yt-dev] Re: Some advice on an unusual field case

Ok, in *that* case, I think we might be able to mock up a way of reading a given file at a time in total for one particle type, then iterating for the other particle type. The other option that immediately comes to mind, which isn't precisely ideal, would be to do a dual iteration over chunks using cloned data sources. I'm sure there is a better way but it's not immediately coming to me. Although, maybe this would be a good match for the particle_operation function in octree_subset. In principle the gas particles should be the nearest neighbors to the tracer particles, right? On Wed, Aug 26, 2020 at 10:51 AM John ZuHone wrote:

Hi Matt,

Just so I am completely sure I understand, are we operating on the assumption that the tracer particles will *not* be in the same *file* (not necessarily chunk) as the gas particles they're assigned to?

Hmm, good question. I do not know how this works in terms of multiple files (I always just dump one file per snapshot). But maybe let’s assume they are in the same file.
