I am trying to calculate the shear stress over a wall in a 2D asymmetric model. I run the sim to good convergence and request the output in surface integrals tab -> wall fluxes -> shear stress.
My issue is that the value reported is in "(Pascal)(m^2)" which leads me to believe Fluent is outputting a force, not a stress. If that was the case I would expect that if I request the axial force along that same wall (x-direction force) I would get the same number (in Newtons); however, this isn't the case. The numbers do not agree to any reasonable percent error.
Am I looking at this wrong? Why is Fluent reporting shear stress in (Pascal)(m^2)?
