Hi ParaView-users,

Hi Stephane,

According to wikipedia - http://en.wikipedia.org/wiki/Skin_friction_lines - you need the "wall shear stress" field first!?

Best regards,
Bruno

I have found how to plot skin friction lines with paraview. Thanks to lovecraft22 for his help.

In OpenFOAM type the command wallShearStress -latestTime.

Then in ParaView, menu Tools, Manage Plugins, SurfaceLIC, select the auto load button (cross). Maybe restart ParaView to have the plugin already loaded when you start ParaView. Then select your part (wall part) in the pipeline. Go to its display tab. Scroll down and set SurfaceLIC for Style Representation and set wallShearStress in your Line Integral Convolution Vectors.

Be carefull because it requires a lot of memory.

Stephane.
