streamline in 3D geometry
 
Hi dear Foamers!

I have a 3D rectangular straight pipe.
There are secondary flows (addition to main flow) in corners.
What's your idea to plot this secondary flow's streamline in planes normal to main flow?
Can I do it by ParaView? how ?

Tanx so much

secondary flow:
make a slice, then use the surfacevectors filter and then the glyph filter!

Thanks very much dear nima
Would you explain me what is differnet between "glyph" and "stream line" tool?

Glymph makes vectors, streamlines makes streamlines.

Hi Nima,
I am simulating blood flow in an artery and my streamlines doesn't start from inlet and their shape is swirling instead of straight through the artery (pipe). do u have any idea what the problem can be?
I have attached the pic
thanks,

Dear hesam :)

welcome to froum, but you choose wrong forum to ask your question :P, its OpenFOAM group not! CFX one :), however your pic is so poor in quality and nothing is clear
