Okay good! Glad that works with the OpenPMD reader. As for the ADIOS readers, I’ll bring up the file series support with the ADIOS team, though it sounds like in your case you’ll just stick with the OpenPMD reader and not use the ADIOS Image reader.
I asked about the ADIOS 2.10 release and it’s going to start soon (in the next week). If that gets finished before the ParaView 5.12 release process is finished, we plan to switch that to use 2.10, in which case the OpenPMD reader and other ADIOS readers would be able to read BP5 files on Windows.
