[vtkusers] Point data with vtkUnstructuredGridReader

[Justin Pogacnik]

Hi all,

I'm trying to use Python to read an unstructured grid file (vtk format) that I wrote for output from a research code. The vtk file loads fine in Paraview, so it should be in order.

The vtk file has 7 scalar arrays of point data and one vector array of point data. However, when I print the point data, only 2 arrays are found -- the first scalar array (elementID) and the last (only) vector array (permeability).

Here is the essential part of my python script:
from vtk import *

filename = 'VTKoutput/FEHM_mesh4_2.vtk'

vtkgrid = vtkUnstructuredGridReader()
name = vtkgrid.SetFileName(filename)
vtkgrid.Update()

print vtkgrid.GetOutput().GetPointData()

I'm happy to pass along the small test vtk file too if it'd be helpful. Also, I'm running vtk-5.10 on Mac OSX 10.7.5.

Thanks in advance,

Justin
