[yt-users] loading Gadget outputs

[Molly Peeples]

Hi folks,

I am trying to read in a Gadget output that’s split into 16 hdf5 files (fwiw, it’s an EAGLE output, and so “should” be similar to the OWLS format). I need to be able to analyze / render the entire output, not just one of the pieces, but I haven’t been able to figure out how to actually load them (akin to how for Enzo yt figures out that there are a lot of cpu outputs in a directory).

I have taken a look at http://yt-project.org/doc/cookbook/owls_notebook.html#owls-notebook, but even there in the example, it’s just reading in the one output and ignoring the other 7 in the example tarball. And there I was having trouble tracking down what n_ref and over_refine_factor refer to.

Interestingly, if I load just the single hdf5s, I can get ProjectionPlots to work but not SlicePlots (which insist there’s “zero dynamic range” with “Min = Max = 0.00000”.)

FWIW, yt.__version__ gives me 3.3.1. (And major thanks to Nathan for getting that installation to go smoothly!!)

Suggestions?
