Hello all.
Could someone tell me if there is a simple way to get Normals
consistency over a multi-block dataset that contains only structured
surfaces grids?
Here is my problem: I have a multi-zone Tecplot file that contains the
skin of the right part of an aircraft, so the skin is NOT closed in the
symmetry plane. The skin is a collection of structured IxJ ordered
surface grids. The orientation of the surface grids are not consistent,
some grids having normals pointing outward, other grids having normals
pointing inward, and I need all normals pointing the same direction for
Surface Flow integration.
The Tecplot reader gives a multi-block dataset and I am using these
filters for rendering:
Tecplot reader->Extract Surface->Generate Surface Normals
The Generate Surface Normals filter is used with Consistency property on
(the default).
Also rendering with light is OK, adding the NormalGlyph filter shows
that normals are still inconsistent, each surface grid keeping its
orientation, and using the Surface Flow filter with any vector gives bad
results.
Thank you in advance for any suggestion.
Best regards.
