Step-2: Data structures and my first sweeper

In this step, we will dig a bit deeper into the data structures of pySDC and work with our first SDC sweeper.

• Part A: Step data structure. The description dictionary, and the step, level and problem it creates.

• Part B: My first sweeper. One IMEX SDC step, done by hand with the sweeper’s routines.

• Part C: Using pySDC’s frontend. The same with a controller, which is how pySDC is normally used.

Each part is a Python script in jupytext “percent” format: run it with python, open it as a notebook in Jupyter, or read it on the website, where it is executed with every build.
