A full Stokes subgrid model for simulation of grounding line migration in ice sheets
Gong Cheng, Per Lötstedt, Lina von Sydow
The full Stokes equations are solved by a finite element method for simulation of large ice sheets and glaciers. The simulation is particularly sensitive to the discretization of t…
Parameter sensitivity analysis of dynamic ice sheet models-Numerical computations
Gong Cheng, Per Lötstedt
The friction coefficient and the base topography of a stationary and a dynamic ice sheet are perturbed in two models for the ice: the full Stokes equations and the shallow shelf ap…
Parameter sensitivity analysis of dynamic ice sheet models
Gong Cheng, Per Lötstedt
The velocity field and the height at the surface of a dynamic ice sheet are observed. The ice sheets are modeled by the full Stokes equations and shallow shelf/shelfy stream approx…
Anisotropic Radial Basis Function Methods for Continental Size Ice Sheet Simulations
Gong Cheng, Victor Shcherbakov
In this paper we develop and implement anisotropic radial basis function methods for simulating the dynamics of ice sheets and glaciers. We test the methods on two problems: the we…
Accurate and stable time stepping in ice sheet modeling
Gong Cheng, Per Lötstedt, Lina von Sydow
In this paper we introduce adaptive time step control for simulation of evolution of ice sheets. The discretization error in the approximations is estimated using "Milne's device"…
