Line 394:
At the end of the day, it is still not correct to say that finite difference method is a type of finite element. The finite difference method has its own derivations, its own analysis, and its own proofs of convergence. At most, you can say that a large classes of problems that can be solved with finite difference can also be solved in a finite element framework. And even this statement would need some good references. [[User:Art187|Art187]] did provide some examples above, but a statement of such generality would need good references to back it up.

: The book ''Numerical Methods for Partial Differential Equations'' By G. Evans, J. Blackledge, P. Yardley has its 4 chapters on FDM before introducing FEMs in chapter 5. So it might a good source to use here. I haven't actually read this article, and I'm probably not going to do that anytime soon... because even shorter ones on these topics are pretty badly written around here.
