    There is no tutorial program for + time-dependent problems!

    + +

    + While there are a number of projects in which deal.II is used to + write solvers for time-dependent problems, there is indeed no + tutorial program showing this. The reason for this is two-fold: + first, writing tutorial programs takes awfully long, on the order of + at least one full work week, and a time-dependent program would + likely be large and complex so may even take longer. These days, the + main authors of the library unfortunately lack the time for projects + of this size unless it would be directly related to one of their + ongoing projects, and would therefore be a side-product of what they + do anyway. +

    + +

    + The second reason is that over time we have found out that there is + not much common ground in time-dependent solvers: most of our + time-dependent projects build on deal.II serve very different + purposes, from research into error estimators to solving actual + engineering problems. They may change the mesh between each + successive step, once in a while, or never. They may use explicit or + implicit time stepping schemes. Since they differ in so many + aspects, there are only few aspects specific to their + time-dependentness that can be moved to the library, and example + programs would be very different depending on the purpose for which + it was written. Furthermore, unlike most of the other tutorial + programs, it may not serve as a template for your own project unless + it happens to have the same objectives. It may therefore not be + terribly useful to a lot of people. +

    + +

    + That said, if someone has a nice program to contribute as an example + program: we would be delighted to take it in! +

    + +

    I want to contribute to the development of deal.II!
