[Paraview] [paraview] visualize higher order element.

[Andy Bauer]

Hi Mathi,

When I looked at the file in ParaView it seems like the connectivity is
wrong with your cells. If you try the Clean to Grid filter that should fix
your problem. I would suggest fixing the connectivity though as the best
way to manage the data since the Clean to Grid filter will merge coincident
points and may inadvertently mess up your point data fields for the
coincident points. Note that the Clean to Grid filter reduced the number of
points in your grid from 2,006,480 to 451,792.

Cheers,
Andy
