155 Gordon Palmer HallTitle: A Parallel Computational Model for 3D Thermo-Mechanical Stokes Flow Simulations of Ice Sheets Abstract: In this talk we focuses on the development of an efficient, three-dimensional, thermo-mechanically coupled, nonlinear Stokes flow computational model for ice sheet simulation. The model features stable and high-order accurate discretizations on variable resolution grids. In particular, we employ a

228 Gordon Palmer Hall Tuscaloosa, AL, United StatesLopsided PMHSS method for Complex Systems Based on the preconditioned modified Hermitian and skew-Hermitian splitting (PMHSS) iteration method, we introduce a lopsided PMHSS (LPMHSS) iteration method for solving a broad class of complex symmetric linear systems. The convergence properties of the LPMHSS method are analyzed, which show that, under a loose restriction on parameter $\alpha$,

228 Gordon Palmer Hall Tuscaloosa, AL, United StatesEntropy Satisfying Numerical Methods for Fokker-Planck-type Equations Kinetic Fokker-Planck equations arise in many applications, and thus there has been considerable interest in the development of accurate numerical methods to solve them. The peculiar feature of these models is that the transient solution converges to certain equilibrium when time becomes large. For the numerical method to

Taking advantage of the Toeplitz matrix structure of the time-space discretization, a fast and
