Dear yt users,

I am trying to make covering_grid from an enzo simulation. The code is very simple: (somewhat sloppy since it's running with ipython. )

ds=yt.load("data0201")

What is the output of "ds.print_stats()" for this dataset?  I'm wondering if your covering grid is running off the edge of the simulation domain.

 

ad_c=ds.covering_grid(level=3, left_edge=0.4375, dims=[64,64,64])

ad_c["x"]

where the ad_c["x"] will give an Index Error on my desktop. However, the same piece of code runs great in a different machine. The version of yt are the same in both machines, which is 3.0.2. Both of them installed yt through anaconda. The error message I got was following. Thanks for your help!
