Hi Amogh,

The wall shear stress is inherently a scalar quantity because it represents the magnitude of the force per unit area acting parallel to the surface.
 
And  LIC in Ensight only works for vectors. BL_CfTau will return a scalar variable, not a vector.
To plot surface LIC it is better to use a velocity vector as it gives a better representation of flow directions. A surface offset of 0.01 would be suitable.
