icepack is a library for modeling the flow of ice sheets and glaciers using the finite element method.
For more information and installation instructions, see the project webpage.
Once you've installed icepack, the directory
notebooks/tutorials/ contains several Jupyter notebooks with demonstrations of the main features of icepack to get you started.
notebooks/how-to contains more advanced material for when you've got a good feel for how things work.
Some of these demos use real data, for which you'll need to have an account with NASA EarthData.
