Journal ArticleDOI
Using the material-point method to model sea ice dynamics
TL;DR: The material point method (MPM) as mentioned in this paper is a numerical method for continuum mechanics that combines the best aspects of Lagrangian and Eulerian discretizations to model convection naturally.
Journal ArticleDOI
Toward a new elastic-decohesive model of Arctic sea ice
Deborah Sulsky,Kara J. Peterson +1 more
TL;DR: In this paper, an elastic-decohesive model for sea ice is proposed, motivated by examining satellite observations of the Arctic processed to show ice deformation in the form of divergence, shear and vorticity.
Journal ArticleDOI
A new Control Volume Finite Element Method for the stable and accurate solution of the drift–diffusion equations on general unstructured grids
TL;DR: In this paper, a control volume finite element method with multi-dimensional Scharfetter-gummel upwinding (CVFEM-SG) was proposed for drift-diffusion equations.
Journal ArticleDOI
Optimization-based mesh correction with volume and convexity constraints
TL;DR: This paper formulate volume correction as a constrained optimization problem in which the distance to the source mesh defines an optimization objective, while the prescribed cell volumes, mesh validity and/or cell convexity specify the constraints.
Journal ArticleDOI
Solving PDEs with Intrepid
TL;DR: The mathematical ideas and software design principles incorporated in the Intrepid package are described and representative examples showcasing the use are provided both in the context of numerical PDEs and the more general context of data analysis.
