Ice-sheet simulations and variable resolution meshing for climate applications

 

Conferencia de Max Gunzburger

23 de Agosto del 2017 de 12:00 hrs

In the first part of the talk, a review of the central Voronoi tessellation approach to grid generation is provided. This technology has been shown to provide superior uniform and variable resolution triangular and Voronoi meshes on the sphere, both for global and regional applications. Illustrations given include meshes on the sphere as well as ocean and ice-sheet meshes. The second part of the talk focuses on recent work on the simulation of ice-sheet flows. The hierarchy of mathematical models for ice sheets is discussed after which finite element methods on highly nonuniform tetrahedral meshes are considered. The combination of sophisticated mathematical models and their discretization via finite element methods results in high-accuracy capability for ice-sheet simulations.
