  How can I calculate wall shear stress gradient and oscillatory shear index in a cylinder-like geometry in Fluent?
  
  Thanks

  Wall shear stress is based on gradient of mean velocity. The gradient of wall shear stress will result in matrix, What are you willing to do?

  How can I calculate the gradient of axial shear stress in the radial direction in a cylinder-like geometry?

  One way is to assign that value to an UDS and access then the gradient of UDS. Do not solve the equation for the UDS.
