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 demo/ contains several jupyter notebooks with demonstrations of the main features of icepack. Some of these demos use real data, for which there are some fetching and preprocessing scripts in this repository.
