[yt-users] load spherical polar coordinate data with mesh refinement in HDF5

[Matthew Turk]

Hi Yanfei,

This is possible -- but it will also slow some things down.  You can
use the load_hexahedral_mesh function, and there're examples of this.
This takes away some of the optimizations that regular grids can do,
but we're hoping to add them back in shortly.  Like the other
functions it too takes a geometry argument.
