Some students fail to make the proper settings in Workbench to begin a 2D analysis and end up with a 3D analysis of a surface in the XY plane which is not the same thing.  In Mechanical, if you click on Geometry and look at the Details window, it you don't see Analysis type is 2D and that you selected Plane Strain, then you are in 3D.

The 2D equations of elasticity, in terms of displacements u and v, including Inertia Forces on the RHS and Body Forces X and Y are:
