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

Hi Jonah,

   I am able to load the data to yt now using load_amr_grids(). I notice
that it can also set geometry to spherical. This is great. But to make life
more complicate. Is it possible to let yt know that the grid is
logarithmic? Currently, load_amr_grids() just take left and right edges of
each block. I guess yt assumes the grid is uniform between left and right
edges. Is it possible to provide arrays of coordinate values for each cell
in each block?

Thanks.
