[Paraview] Ensight Reader

[Zhanping Liu]

Hi Werner:

    The problem is due to the inconsistency between the geometry files and
the 'measured geometry' files in terms of ASCII / Binary format. Currently
the VTK EnSight reader assumes that these two kinds of geometry files (and
their respective data attributes --- pressure, temperature, and et al) adopt
the same ASCII / Binary format. Specifically, the geoemtry file (Binary for
your dataset --- the associated data attributes are binary) is first parsed
to determine the type and hence vtkEnSightGoldBinaryReader2 is invoked. This
binary reader is then used to load the 'measured geometry' file (ASCII for
your dataset --- the associated 'measured' data attributes are ASCII),
causing the problem.

   If you make the whole dataset (including the geometry files and the data
sttributes) use the same ASCII/Binary format, the problem should disappear.
