The model displays as shown in the following image.
Note The surface force is applied normal to the surface by default. Prior to processing the elements for analysis, the normal direction is not known. The arrows with the horizontal line at the tip are used to indicate normal forces. They always point downward within the FEA Editor. In the Results environment, the true direction will be shown.
