Hey Sam, It's used in the 3.0 testing: yt/utilities/lib/tests/test_alt_ray_tracers.py has it in a couple places. -Matt On Tue, Feb 26, 2013 at 11:49 AM, Sam Skillman wrote:

Seems like I can do [:,::-1] for gles, gres, and [::-1] for levels, and subtract by 1 and it will work. Should amrspace return them like this? I don't know what else amrspace is used for.

Hi all, I'm trying to figure out how to use amrspace combined with load_amr_grids to create a decently complex amr structure for testing. However, I can't find any example of doing such a thing in any documentation or source. My attempt below fails in that it creates no level-0 grids, and also has the ordering of grids messed up grid 0 is level 4.

Any advice on combining these two functions?

No, it doesn't -- it's not supposed to. What I was idly speculating about in IRC was to create something to feed into load_amr_grids via the hierarchy created here; i.e., iterating over these to get the left/right edges of the grids, and using np.random.random() for the data, then supplying that to load_amr_grids. But, I think you should skip messing with it, like you say. Next week one of my agenda items at UCSC is to come up with an AMR-ful random parameter file. :) -Matt On Tue, Feb 26, 2013 at 2:36 PM, Sam Skillman wrote:

It doesn't actually instantiate a pf though with it, from what I can tell.

I'm going to skip messing with this for now.

Thanks, Sam
