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! Dan Whalen

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. -Matt On Fri, Aug 29, 2014 at 12:25 AM, Daniel Whalen <dwhalen1999@gmail.com> wrote:

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:

My suggestion would be to fake it by setting the right edges to be 2pi and pi, and feeding in a faux-3D dataset. -Matt

So we're actually *not* getting a 1D dataset then, in the sense that we will be duplicating zones. On Sep 26, 2014, at 3:16 PM, Matthew Turk <matthewturk@gmail.com> wrote:

No, sorry -- specify one cell along the 2nd and 3rd dimensions, but have them span the full domain. THis is what we do internally for 1D and 2D data for cartesian (and in FLASH, for instance, for non-Cartesian) but here it's being done manually at ingest.
