Hi all,

I'm trying to load in some data from an ASCII VTK file (attached for reference) that I created following the guidelines here: http://www.vtk.org/wp-content/uploads/2015/04/file-formats.pdf. I can load this file into Visit and I was hoping that to load it into yt would be as simple as :

ds = yt.load("lid_driven_cavity_20.vtk")

When I try that however I get the error message:

Traceback (most recent call last):

  File "visualization.py", line 3, in <module>

    ds = yt.load("lid_driven_cavity_20.vtk")

  File "C:\Users\Dave\Anaconda2\lib\site-packages\yt\convenience.py", line 84, in load

    return candidates[0](*args, **kwargs)

    self.domain_left_edge = grid['left_edge']

KeyError: 'left_edge'

Is it possible to load in such a file to yt? If not, since I'm writing my own data file, how could I edit it to make it readable by yt?

Thanks in advance,

Lukas
