[Paraview] Clean Grid and Average Point Data

[Andy Bauer]

Hi Tristan,

There are a couple of things you can try. The best but most complex is
probably the programmable filter where you merge the points yourself and do
the averaging for the point values. The other thing you can try is using
the point data to cell data filter, then use the clean to grid filter and
finally use the cell data to point data filter. This may due more averaging
than you would like for your results. Other than that, did you get any
feedback on the deal.II mailing list?

Regards,
Andy
