Hi,

I've plotted the Wall Shear X on two surfaces and where it's negative I get boundary layer separation (see image). I have put surface streamlines so that I can see the circulating fluid paths but CFD-Post only ever puts the streamlines so that they go around the separation region, and I've put 1000's of streamlines on.

How can I get CFD-Post to put streamlines in the separation region?

Thanks

Manually define a point in the separated region and use that as the seed point for a streamline.
