Elmer/Ice: Open Source Finite Element Software for Ice Sheet, Glaciers and Ice Flow Modelling. Elmer/Ice is a full-Stokes, finite element, ice sheet / ice flow model. The aim of this website is to present the capabilities of Elmer/Ice and to distribute course materials and tutorials. Elmer/Ice is an add-on package to Elmer, which is a multi-physics FEM suite mainly developed by CSC-IT Center for Science Ltd., Espoo, Finland. Initially started by CSC, IGE and ILTS, currently multiple institutions and individuals contribute to the development of Elmer/Ice.
