The ISMIP-HOM benchmark experiments performed using the Finite-Element code Elmer
International audience The aim of this paper is to describe in detail how the benchmark tests ISMIP-HOM (Ice Sheet Model Intercomparison Project-Higher-Order ice-sheet Model) have been performed using the open source finite element (FE) code Elmer (http://www.csc.fi/elmer).
