Dear Foamers,
I have a question about streamlines. I know how to control them in paraview, but I wonder if it is possible to confine them to a certain wall/patch distance just using paraview? I already have described my problem here: http://www.cfd-online.com/Forums/ope...reamlines.html Thanks for any help! Best regards Julian

Greetings Julian,
I had to read the other thread, in order to understand what you meant: you want the streamlines only on the patch surface. I was initially thinking you were referring to restraining the streamlines for a certain distance from a patch. In ParaView has got "Surface LIC" (or "SurfaceLIC"), a special plug-in that can represent streamlines on surfaces. You can find some information about this here on the CFD-Online forums if you search for it. The thread on this topic that I'm most familiar with is this one: http://www.cfd-online.com/Forums/par...ic-plugin.html Best regards, Bruno

Dear Bruno,
first of all, thanks for your reply. Quote:
http://www.openfoam.org/version2.2.0...processing.php (=> see: new wallBoundedStreamLine - creates streamlines in VTK format to show near-wall flow, as shown for the motorbike tutorial case) As explained in the other threat, this does not work in my case. Quote:
I applied it to my object surface patch and loaded the according velocity. Seems to work and give me these LIC streamlines. I just wonder, is it the same as the wallBoundedStreamlines? Anyway, I just want to show separated flow regions, so with wallGradU this should be possible to do. Thanks again and best regards Julian
