Is it possible to conduct fatigue ('Durability', in NX-speak) evaluations with FEM's composed of 2D meshes, rather than 3D elements?
Running a quick test with a 2D FEM seems to indicate this isn't possible (solve fails, indicating a problem with the XML input deck).

But that being said, while I've personally never done any FEA-based fatigue analysis, I can remember back when we used to draw Mohr's Circles and calculate fatigue life based on the frequency that loads were varied, if I recall correctly, we had to look at these as 3D problems so it just might be that 3D (solid elements) are a prerequisite to using codes which can predict the fatigue life of a model under cyclic stresses.

To an Engineer, the glass is twice as big as it needs to be.
