Similarly, the results on a planar element are given by default in the local coordinate system of the element. Thus Fyy is a normal force in the local Y direction, and in a plane perpendicular to the Y (local) axis.
The only exceptions are the section cuts on the planar elements. In this case, the results are expressed in the local coordinate system of the planar element on which they are defined. However, in Advance Design this setting can be modified using the Options tab of the Results dialog box (Alt + Z).
Thus, for a plate with 2 supports on which a uniform load is applied like the one above, the results for Mxx may be:
