[yt-users] Cylindrical VTK data

[Elizabeth Tasker]

Hi everyone,

We have a file created with Fargo 3D that’s been exported to Athena VTK format. When we try and load this into yt 3.0, we hit the error:


In [1]: ds = yt.load("gasdens1000.vtk")
---------------------------------------------------------------------------

   413                   " This will be corrected automatically if it is not the case.")

KeyError: ‘left_edge'



I’m guessing this is because the data set is in polar coordinates? Is that right? I’ve seen that yt can handle polars in FLASH but does it need to be explicitly FLASH data? 

Thanks very much,

Elizabeth
