Viscous contact problems in glaciology

Thesis

Viscous contact problems describe the time evolution of fluid flows in contact with a surface from which they can detach and reattach. They can be modelled by coupling the Stokes equations with contact boundary conditions and a free boundary equation that evolves the geometry of the domain occupied by the fluid. These problems are of particular importance in glaciology, where they arise in the study of grounding lines and subglacial cavities. This work investigates the numerical approximat...
