Public Data Access Overview / Discussion Forum

Hi Dylan,

I have found there are some analysis packages (e.g. yt, sator, paicos and scida) which claim to support arepo data. Which one is the most suitable for TNG?

Thank you and best wishes.

I would say that:

• yt is the most complex and feature rich, but the least suited to TNG.
• sator is not under active development.
• paicos and scida seem to have some similar features (I have never used paicos).

Then:

• scida uses dask with the idea of automatically scaling large computations. it is not specific to arepo, but aims to be more general.
• paicos is arepo-specific and looks like it has some related built-in features, like visualization tasks.

Thanks for your comment.

What about pynbody?

This has been in development for many years, and is somewhat general (multi-code), so I would view it as a lightweight alternative to yt, or a more developed (but less specialized) version of paicos.

It was very nice of you.

As an update: the new temet package may be of interest. It is rather specific to cosmological simulations, particularly IllustrisTNG and data available here on the TNG website.

Awesome! It is the best for TNG.
