Hi Carla, This functionality was recently implemented and is in the development version, but not yet in the stable. We're hoping for a release very shortly, but you can also try the dev version if you'd like! -Matt On Tue, Mar 29, 2016 at 8:55 AM, Carla Bernhardt <carla.j.bernhardt@gmail.com> wrote:

Hi All,

A follow-up question: In using arbitrary_grid (but with enzo data), how does one then extract a field of an arbitrary_grid? I tried arbgrid["density"] as I have done with a smoothed_covering_grid object, but it does not work (here is the traceback I got).

Thanks, Carla

Hi Desika,

Yup, this can be done reasonably easily using either the .arbitrary_grid object (which was designed for this) or the interface to the arbitrary grid that's in the development version, which is ds.r[ ... ] where the ... is some combination of bounds and steps.

Hi All,

Is it possible to deposit the particles from a gadget data set onto a uniform grid in yt? Or, could it be possible to trick the octree deposition into doing it by forcing no refinements, but some sort of native grid resolution?

thanks, desika
