[yt-users] Unstructured grid yt support‏‏ -question

[Ariadna Murguia]

Hi!
Don't worry, I'm thankful for your help. My data is a vtk legacy file for unstructured grid. The coordinates are of the vertex, but the values of the variables are cell-center. I'm available on thursday and on friday before noon (PDT). Are you available?
