Hi Matt, I ran the script accordingly and the results came out: Not smoothed 143496 0 Smoothed 143496 0 and "143496" is exact the total number of my grids. Is there any clue to this problem? Many thanks, Jia -Hung -------------Previous Email----------------- Hi Jia-Hung, Sorry for the delay! The key error you're seeing is because yt was unable to fill in all of the cells needed for the smoothed covering grid. Can you try this, and see what happens? ngood = 0 nbad = 0 for g in pf.h.grids: try: g.retrieve_ghost_zones(1, ["Ones"], smoothed=False) except KeyError: nbad += 1 cnotinue ngood += 1 print "Not smoothed", ngood, nbad ngood = 0 nbad = 0 for g in pf.h.grids: try: g.retrieve_ghost_zones(1, ["Ones"], smoothed=True) except KeyError: nbad += 1 cnotinue ngood += 1 print "Smoothed", ngood, nbad and let us know the results?

Dear all,
I want to say thank you to all of you for making how powerful and convenient yt is. I really appreciate everything you have done. I?m now using yt 2.6 version and trying to construct our AMR code named ?GAMER? frontend to yt.
So far I have several preliminary results that I could plot picture with projection /slice/ contour /radial profile successfully, and the outcome pictures all seem fine. However when I tried to plot ?3D Surface and Sketchfab?, I failed.
It popped out some error messages. There exist some covering problems in my data structure. Actually this question also happened when I tried to plot ?VorticityMagnitude?. I couldn?t figure it out, and every data value and positions seem fine when I plot pictures in projection and slice.
Therefore, I believe there is some fundamental problem that I am too careless to pay attention to. Could anyone help me with this problem? Thank you in advance.
