Glyph at a fixed distance from the domain boundary

Hi,

This is an image with glyphs that have the direction of the velocity but they are not scaled.

Cattura

I do not want to display the glyphs that are near the walls. there is an option to display only the glyphs that are at a distance higher than X from the domain boundary?

You can clip your domain and display the glyphs only in the clipped domain, while displaying the whole domain in the same image.
