[Paraview] Extract Wall -- 3d geometry

[Aurélien Marsan]

Hi,

I finally have found a simple solution : instead of exporting the solution
in the CGNS format (from CFX), I now use Ensight files which Paraview is
able to read and which includes the boundaries. (accessible using the
ExtractBlock Filter)

However, it would be great to have a Filter that would be able to detect
the edges (discontinuity of curvature or of the the normal vector ?) on the
surface resulting from the ExtractSurface filter, and that will work on
both structured and unstructured Multiblock meshes.

Does that make sense to you ?

Regards,

Aurélien
