Hey,

At the moment the objective is using yt with the C series of Chimera models, which are logically cartesian. Later runs use the yin-yang grid, but structuring the reader to use that date is a later endeavor.

Ronan, is it still logically Cartesian?  or is this with the yin yang mesh in Chimera?

Hello all,

I’ve been in contact with Dr. ZuHone for the last few weeks about my efforts to create a new yt frontend for Chimera data, and he directed me here for further assistance.

Chimera is a unigrid dataset with spherical polar coordinates and a nonlinear r-axis scaling; as a result, it needs a custom mesh rather than the AMR grids or SemiStructured meshes present in some of the existing frontends. The Chimera datafiles all contain arrays which detail the edge positions of the gridblocks, so creating an array of grid-edge coordinates is fairly trivial. Theoretically, I would expect the transfer of this coordinate array into a yt mesh object would be fairly straightforward, but I don’t have enough familiarity with the functionality of the Unstructured Mesh class to do so without some guidance. I was hoping that someone here might be able to shed some light on what the contents of this class do and how it functions as a whole, such that I can create one for Chimera.

Many thanks,
-Ronan Hix
