[Paraview] Multiblock Dataset number of points

[Renato Elias]

Hi Rafael and Zhanping,

I've found out what is going on. I've loaded the Rafael's dataset (we are
co-workers at the same lab) in PV-3.6 and PV-3.4 as well. The confusion is
due to the Ensight file format. Rafael is using Ensight 6 format (not the
Gold one). In Ensight 6, the point coordinates for the whole grid is firstly
inserted in the geometry file, in the "coordinates" section, and the
following parts are defined by cells that use only some of these points.
Note that the cell parts do not have any information regarding points. Just
cell incidences are listed. In order to show the correct number of points
that each part uses, ParaView should have some algorithm to count the points
actually used.

The main difference between Ensight 6 and Ensight Gold is that in Ensight
Gold the point coordinates must be informed for each part.

Here goes the data (if you're still interested)

Renato.
