CFD particle traces not filling in across the seed grid

Hello. I’ve been trying to get a particle trace filter to fill in across the entire inlet of my flow geometry. I’ve adjusted the spacing and grid size without any improvement.

Hi @klindner,

Thanks for sharing your question here on Forum.
It looks normal, but the issue here is that is quite hard to centralize the particle tracer, so it is always being some millimeter above or below the center, causing the misleading. The easy way to deal with that is putting 2 particle tracers, one above the center and another one below the center, and then you have all the traces in the body for sure (please look at the video below).

Please let me know if this helps you and do not hesitate to reach out in case of any other questions.
