ParaView: 1D AMReX/BoxLib Grid Data Support

[jbuffaloe]

Hi all, I have this question up over on the ParaView forums https://discourse.paraview.org/t/1d-amrex-boxlib-grid-data-support/17197/2 but figured that it would be good to ask/have a copy of for others here as well.

Is it even theoretically possible for the ParaView BoxLib/AMReX grid-based reader to support 1D AMReX plotfiles? Our 2D data from the portion of our grid-based code that has AMReX support works in ParaView without any issues, but 1D keeps throwing up ‘Invalid AMR Box’ errors (for multiple datasets and ParaView versions on multiple machines). Since, separately, VisIt only offers 2D/3D support through the specific BoxLib2D and BoxLib3D readers, I've been trying to figure out if this is a pure ParaView/ParaView's reader issue, a subtle bug affecting the plotfile output in our code, or something deeper with the data structure and how these kinds of readers work (although we've successfully used yt in the past for 1D data).

The other forum post has a custom 1D problem plotfile, but here's also a 1D plotfile from a simple hydro advection problem if that is helpful:
