Hello, 

I don't know what your application is but in general 2D analyses are most relevant when there is some level of symmetry, which allows for reducing the order of the system.

The farther you move away from this assumption, the more 3-dimensional effects and other interactions may come into play, reducing the accuracy of a 2D model.
