wall shear stress

sarfaraz · November 14, 2014, 08:29

hello,
i have completed simulation with 90 degree bend pipe. now i want to find out the wall shear stress across the bend section. i don't know the coordinating points.

Thanks in advance for the help

Wall shear stress is a variable which can be displayed on the wall boundary object in CFD-Post. I do not know what you mean by coordinating points.

thanks for your replay

Actually i want to calculate the wall shear stress along the axial length of 90 degree bend pipe in cfx post. i had tried to create a plan through this plan a polyline has drawn.

but this polyline has insufficient number of points to create a smooth graph.
Do you have any idea of creating a ployline at the wall of bent pipe along the axial length.

thank you

Can you draw an image of what you want to do? Where do you want the polyline to go?
