Each of the tutorials (T1–T12) will usually start with a general discussion where we will talk about the goals of the current exercise set and discuss the related physical and numerical issues. You will work on the exercises during the tutorials while supervised by the tutors. Bringing your own laptop is encouraged, but we will provide laptops for those who cannot bring their own. To pass the tutorials, you need to present results to at least half the exercises of tutorials T4–T12, so you should bring a plot of your results to the following week’s tutorials. In case you cannot make it to one of the tutorials, or the time during the tutorials is insufficient, you can solve the problems at home and present the results in the following tutorials. (Also, keep in mind that the later exercises build upon the earlier ones, so you will need to complete your codes anyway.) We will provide some example code fragments during – and especially at the end of – each tutorial which you can use as basis for the next one. You will be graded according to your contributions to the general discussions and on the physical and numerical interpretation of the results, but not on your programming skills. If you use your own laptop, you will need a C/C++ or Fortran compiler (e.g., gcc or gfortran), a text editor (such as emacs or vim), and a program to produce graphs (for example, gnuplot). Additionally, wireless connectivity (eduroam) would be very useful.
