Creating custom vectors on plane

ParaView Support
1

Hi

I have the time averaged X,Y,Z velocity of a pipe flow and I have exported them into paraview format. Now i want to draw the vectors on the plane or cross-section of the pipe with my time averaged vectors field. I have created a calculator as: ihatxvel+jhatyvel+khat*zvel, and using surface vectors but it is not plotting them. What is the issue?

I am also seeing a weird thing where I can see both the surface vectors and the axial vectors, but i want to see only the surface vectors.

I’m not totally sure I understand what you want to do. By “draw the vectors.” I assume you mean that you want to have little arrows or something like that pointing in the direction of the flow. If that is the case, then Glyph is the filter you are looking for. The steps you need for that are:

  1. Combine the component fields into a vector field. The way you are doing it with the Calculator filter is fine. Recent versions of ParaView also have a filter named Merge Vector Components that makes this process a little easier.
  2. Add the Slice filter Screenshot 2026-08-10 at 8.40.36 AM|x33 and position the slice plane at the cross section of the pipe where you want to see the vector field.
  3. Add the Glyph filter Screenshot 2026-08-10 at 8.41.57 AM and select your vectors to orient and (optionally) scale the arrows. You may also need to modify the Scale Factor to get them sized right.

Yes but how to draw the vectors on the cross-section. For that I draw glyph on surface vectors and do constraint mode parallel. Is that fine?
