Indicating a specific number of streamlines with a threshold for their length

Hi all,

I’m trying to find the length of streamlines in my domain. I want to indicate a specific number of streamlines, whose length is bigger than a value. I also need that these streamlines to be equally distributed in the domain. I know that I can find their length with Cell Size filter and then set a threshold for them. But instead of using resolution in streamlines, I need only a fixed number of streamlines (e.g. 1000 lines) that are bigger than a value and are distributed equally in the domain. Thanks in advance for any help.
