[yt-users] load structured mesh

[John Zuhone]

Hi Andrea,

yt has some support for axisymmetric grids in 2D, so you won’t need to convert to a 3D array.

The bigger issue is the logarithmic grid spacing. This is currently being worked on, but is in a very early state. Currently what it does is use “logr” as the coordinate instead of r, which may not be very ideal for every situation. A lot of yt functionality is probably not compatible with this way of doing things. 

Nevertheless, if you would like to explore it further, let us know. 

Best,

John Z
