Hi Matt, I'm coming back to this thread... From the docstring: connectivity : array_like This should be of size (N,8) where N is the number of zones. coordinates : array_like This should be of size (M,3) where M is the number of vertices indicated in the connectivity matrix. How would this work for 1D data? Or would it? Best, John On Aug 29, 2014, at 6:40 AM, Matthew Turk <matthewturk@gmail.com> wrote:

Hi Dan,

The load_hexahedral_mesh option will handle arbitrarily spaced coordinate systems. It accepts the cell boundaries and the cell values (so there must be N+1 boundaries) and the argument geometry='spherical' will then have it interpret them as spherical coordinates. That should work to get log spaced radius zones.

I am trying to use yt to visualize 3D spherical coordinate data sets created with the ZEUS-MP code. I know yt can directly read in such data, but are there any issues when the grid is ratioed in the radial coordinate (ie, logarithmically spaced zones in radius).

Thanks!
