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) has been performed using the open-Source finite element code Elmer (http://www.csc.fi/elmer). The ISMIP-HOM setup consists...
