[yt-users] Not able to read 2D BoxLib files

[Andrew Myers]

Hi Mani,

To my knowledge, no one has ever used yt with 2D Orion data. I'm not sure
if any of the other BoxLib codes support 2D. I think the reason the Orion
code is getting called is because yt can tell your dataset uses BoxLib, but
not that it belongs to any of the other BoxLib-based codes (Nyx, Castro, or
Maestro), so it falls back to Orion.

What simulation code generated this dataset? If it's not one of Nyx,
Castro, Maestro, or Orion, then you'll probably need to write a new
frontend for your data.
