Wall_shear_stress on Field Files

ParaView Support
1

I am trying to extract wall shear stress or gradient dU/dy across the airfoil profile using gradient and methods proposed in Manipulation of field files - ParaView Support - ParaView and Calculation of Drag, Wall shear stress, Lift - ParaView Support - ParaView. However I am unable to process the mesh. It would be helpful if you can tell me

  1. To plot the dU/dy across the airfoil surface.
  2. Get the product of dU/dy * mu * surface normals by performing generate surface normals and use the value of the gradient.

Thank you
