Glyph: how to avoid the plot of vectors perpendicular to boundaries?

Dear all,

In paraview if I select glyph scaling off and the velocity magnitude is 0, the glyphs are orientated in the x-direction (as in the picture enclosed) [look like they are getting through the boundary wall]
is there a way to make those horizontal glyphs disappear?

Did you add boundary patches along with your internal mesh, maybe try only internal mesh.

Ah Ok, we can do this way:
(from pag166 user-guide) first apply the Cell Centers filter to the case module (Filters -> Alphabetical -> Cell Centers), and
then apply the Glyph filter to the resulting cell centre data.

In this way we plot the vector in the center of the cell, whose magnitude is not zero, so the orientation is not horizontal anymore.
