+ | * Project by Denis Cohen, Juha Hartikainen (Tampere), Peter Råback and Thomas Zwinger (CSC) to apply an Enthalpy formulation to be solved in the ice as well as the bedrock. Starting from simple mixture models (Cuttler et al., 2000), the plan is to develop a system of equations including salinity and liquid phase transport. Updates are being pushed to branch " | ||
