Guided Construction of a 2D TDDFT code

Coding is, for most of us, a painful time-consuming task; the production of even the simplest code piece may require anything from a few minutes to several days of work, with most of the time dedicated to looking for information completely unrelated to the Physics of the problem or the design of the algorithm. Due to this fact, there is obviously not enough time in these sessions to build these three elements from scratch. Hence, we will do a “guided construction”. A preliminary, primitive, code is already written – except for some pieces which we suggest you to fill in. This will speed up the process, but you will still have to dig into the code, and in this way you will learn the manner in which the underlying TDDFT ideas are transformed into a working algorithm. If you wish, you can add any enhancement. This document is the road map for the construction process.
