Hello fellow yt'ers: I'm having some issues with some fields that I don't think are behaving the way they should be in yt. I'm encountering a number of problems with a simple 2D enzo dataset (x and y), so I put together a notebook demonstrating my various issues. https://hub.yt-project.org/nb/727j2j To summarize the weirdness from the notebook: 1) The 'dx' field doesn't seem to be able to be displayed (i.e. when I try to slice it), whereas the 'dy' field is fine. 'dz' even exists, but it's just uniformly 0, as is expected from a 2D dataset. 2) When I try to produce a new field which is 2^GridLevel, I get weird results (ignored levels and more). 3-5) I get strange behavior when trying to make a new field combining GridLevel and 'dy', since GridLevel has twice as many indices as any of the spatial fields (in the z direction no less). This results in some odd behavior when I try to pair various subsets of GridLevel with 'dy'. Any clarification of these ideas is welcome. The docs and source haven't yet revealed what is going on here. Thanks! Cameron -- Cameron Hummels Postdoctoral Researcher Steward Observatory University of Arizona http://chummels.org
