How to show streamlines in specific section

Hi, I would like to ask if there is a way to show streamlines in a specific part of an object. I have a cylinder-shaped object centred around X-axes. Streamlines swirl around the centre. I would like to see results in half of the section of the object where Y>0. I have tried the filter, but it doesn't work because it removes every streamline that crosses the X plane to negative. Any suggestions? Thank you.

Filtering (e.g., specifying
) works fine for me. Not sure what you did, exactly. Alternatively, if you create your geometry such that the volume in which you want to plot the streamlines is a single domain, you could then use the "selection" feature to plot streamlines only in that domain. If that doesn't help, then I suggest you post your .mph file to the forum so we can all see what you did and then, maybe, diagnose the problem.
p.s. Is the problem caused by a specification of where your streamlinesstart? Look at (and experiment with) your settings under "Streamline positioning."
