Run the examples in CI
As @dschwoerer mentioned, it would be useful to run all of the examples as part of the CI. Probably just with a manual trigger in the first instance? Just making sure that they all initialise properly would be a good start, I don't think they necessarily need to run to completion.
Launching them with solver:nout=1 solver:timestep=1 will do the minimal thing that hits all parts
This is a really good idea. One snag could be that nobody has looked at the 2D examples for a long time, and many may need updating to work. A "flagship" 2D example is on my to-do list once I'm done with the SOLPS comparison project. In the meantime I would only count on recycling to work.
