In this chapter, we focus more deeply on a number of aspects relating to the translation of the finite element method into computer code. This
implementation
process can hide some pitfalls. Beyond the syntactic requirements of a given programming language, the need for a high computational efficiency implementation requires a codification that is generally not the immediate translation of what has been seen during theoretical presentation. Efficiency depends on many factors, including the language used and the architecture on which one works. Personal experience can play a role as fundamental as learning from a textbook. Moreover, although spending time searching for a bug in the code or for a more efficient data structure can sometimes appear to be a waste of time, it (almost) never is. For this reason, we wish to propose the present chapter as a sort of “guideline” for trials that the reader can perform on his own, rather that a chapter to be studied in the traditional sense.
