[yt-dev] Creating a new front end for Pluto Xdmf files

Hi, I'm creating a new yt frontend for pluto xdmf static grids (finite volume mesh code). I have a grid.out file which has the values of the left and right cell faces in all directions. Can anyone suggest a way to set up the Hierarchy and Grid classes for this? I'm a bit stuck in this part. It would be really helpful. Regards, Alankar
