The following examples illustrate the functionality of Flopy. After the tutorials, the examples are the best resource for learning the underlying capabilities of FloPy.

The basic set of MODFLOW executables as well as the optional dependency group are both required to run the tutorials.

If the tutorial/example scripts detect that they are running within the repository, they will use local example data. Otherwise they will download example data files where necessary from GitHub.
