[Paraview] using contour plot with xdmf input

[Utkarsh Ayachit]

Stephanie,

The issue seems to be the fact that in the XDMF file you have a whole
lot of duplicated points. Here's my pipeline:

   fault.xmdf -> Clean To Grid -> Cell Data To Point Data

Now I can contour as expected. Clean To Grid will merge duplicate points.
