I am a new guy to use paraview. I am trying to calculate drag force over a sphere but can't add the wall shear stress terms in the calculator filter option. I have tried the "Gradient of Unstructured Data Set" to have the gradients. In the vector option of calculator, I can also see the gradient option.

But how can I calculate drag force now.

Can anybody help please.

Thanks in advance.
