Hello,

the total stress, σ = − pI +τ , where “I” is an Identity matrix, “p” is the hydrostatic pressure, “τ” is the viscoelastic components

force, F =σ .A

In CFD-Post under “Expressions”, calculate first the total stress using total extra-tensor post processor. Then using Expressions, evaluate the area integral of the all the components over the surface on which the force has to be evaluated. Then by getting the appropriate normal vector components on the surface of interest, evaluate all the force components acting on the desired surface.
