Short summary
There are different ways to study the icy continent of Antarctica. One way to understand various processes in Antarctica or to investigate the future of the ice sheet under climate change, is to build a computer model. Several steps are needed to represent how ice flows inside a model. These include for example the derivation of the physical equations, the construction of a coordinate system and the choice of boundary conditions.
