Stream tracer filter unavailable even with vector field data

[path]

Hello, I have a simple lid driven velocity field Exodus file with vel_x and vel_y point data variables. Paraview seems to recognize them as a vel vector with X and Y components and also provides the magnitude. However, stream tracer and all other vector-based filters remain grayed out.

I’m currently using ParaView 5.11.1 for Windows.

You need to add the z component to the vector in the Calculator filter.

Your suggestion worked. Thank you!
