  2. Elements have dimensions as well! The problem is with names. Plate elements are often called 2D elements while solid elements are 3D elements. This makes it a bit funny. After all, you don't know what someone means if they say 2D FEA. They may be referring to a 2D space in your model or to the use of plate elements. I would say that a decade ago (maybe a bit more) using 3D space wasn't very common (due to computing costs). Back then, 2D FEA almost always meant.

It is important for at least two reasons. First, the FEM is able to solve PDEs on almost any arbitrarily shaped region. Second, the method is well suited for use on a large class of PDEs. While it is almost always possible to conceive better methods for a specific PDE on a specific region, the finite element method performs quite well for a large class of PDEs.

Finite element approximation is particularly powerful in 2D and 3D because the method can handle a geometrically complex domain \(\Omega\) with ease. The principal idea is, as in 1D, to divide the domain into cells and use polynomials for approximating a function over a cell The finite element method, as implemented in NDSolve, has been optimized for speed. This optimization comes at a cost. It is common in numerics to be able to trade speed versus memory consumption. This means that a faster implementation will need more memory to solve a problem at hand. It is, however, possible to tune the implemented finite element method through various means to use less.

For example, take the following sentence: The man runs to the store to get a gallon of milk. Runs is a finite verb because it agrees with the subject (man) and because it marks the tense (present tense).
