Re: [yt-users] Odd array size issue

Hi Matt, Sorry to re-visit this issue but while your fix totally solved the previous problem, I have unearthed a second. If I create a scg, the "z" position is correct up to the first & last handful of cells. At this point, is mysteriously starts to decrease along with associate changes in density and acceleration fields. e.g. scg details: AMRSmoothedCoveringGrid (GR_Enzo2_128amr5_zeus_turb_psupp_rr_0001): level=3, left_edge=[ 0. 31. 0.], right_edge=[ 64. 33. 64.], ActiveDimensions=[2048 64 2048] z position for z-index 2035-2047: [ 63.609375 63.640625 63.671875 63.703125 63.734375 63.765625 62.796875 60.828125 57.859375 53.890625 48.921875 42.953125] z position for z-index 0-20: [ 28.015625 21.046875 15.078125 10.109375 6.140625 3.171875 1.203125 0.234375 0.265625 0.296875 0.328125 0.359375 0.390625 0.421875 0.453125 0.484375 0.515625 0.546875 0.578125 0.609375] The same is true in the x direction but the (smaller) y direction is fine: y position for y-index 40-63: [ 32.265625 32.296875 32.328125 32.359375 32.390625 32.421875 32.453125 32.484375 32.515625 32.546875 32.578125 32.609375 32.640625 32.671875 32.703125 32.734375 32.765625 32.796875 32.828125 32.859375 32.890625 32.921875 32.953125] y position for y-index 0-20: [ 31.015625 31.046875 31.078125 31.109375 31.140625 31.171875 31.203125 31.234375 31.265625 31.296875 31.328125 31.359375 31.390625 31.421875 31.453125 31.484375 31.515625 31.546875 31.578125 31.609375] The script that generates that output is here: http://paste.yt-project.org/show/2454/ I actually end up chopping out the middle of my data and using it someplace else, so it's maybe not a problem but it is a bit worrying.

Hi Elizabeth,

Sorry for the delay.  I have identified the problem.

Your covering grid was only selecting level 0 grids.  This resulted in the smoothed covering grid making an early exit.  I've added additional steps to produce grid-free refinement/interpolation to higher-levels in changeset 2cd5fa6d84ae.

Hi Matt,

It's a possiblity; John reverted some changes several weeks ago, but I thought that restored it to the previous operations.  None of the answer tests have thrown anything, and they do test this functionality.

Can you provide a script (pastebinned) that I can run?  And, what's the size of your domain?  32, 32, 32 for extent, and dims of ... 128^3?

Actually, double my usual:

64 x 64 x 64 kpc boxsize 256 root 3 AMR (static grids)

This script produces nothing good:
