can't read openPMD files that use the ADIOS2 format

[BenWibking]

Bug report

Bug summary

The openPMD frontend only reads openPMD files that use the HDF5 format. openPMD files that use the ADIOS2 format cannot be read by yt.

The openPMD-api (https://github.com/openPMD/openPMD-api) provides a Python package that can be used to read any openPMD file, regardless of the backend format chosen.

Code for reproduction

Actual outcome

N/A

Expected outcome

yt should be able to open all openPMD files, regardless of the backend used.

Version Information

• Operating System:
• Python Version:
• yt version:
• Other Libraries (if applicable):

I am happy to help add support for using openPMD-api, but I don't want to duplicate effort if someone is already working on this.

Hi Ben. For what it's worth, I haven't heard of anyone take else working on this already and I'm sure this would a welcome addition. Thanks !

I haven't had a chance to work on it, so it's all yours to work on if you wish.
