Hi all, I'm trying to access Exodus II Data from a [MOOSE](https://mooseframework.inl.gov/) application. I'm following the instructions provided [here](http://yt-project.org/doc/examining/loading_data.html#exodus-ii-data). My particular script is follows: ```python import yt file_name = "results.e" ds = yt.load(file_name, step=-1) time = float(ds.current_time) ad = ds.all_data() ad["connect1", "rho"] ``` where ("connect1", "rho") is a valid field. This script fails on the last line with a traceback and the following error message: ``` RuntimeError: Region right edge[0] < left edge: width = 0.0 ``` The particular MOOSE simulation consists of two, 1D meshes. Would anyone know why I'm getting this error and how to overcome it? Thanks in advance, Andrew
