In 2D axisymmetric cases, are the force reports based on the area of a 360-degree revolved surface?
While post-processing 2D axisymmetric results, the forces reported from the Report > Forces… panel are based on the 360-degree revolved surface area. In other words, the line integral of pressure and shear stresses are internally multiplied by 2.
