Sea-ice dynamics on triangular grids [PDF]
Journal of Computational Physics, 2021 We present a stable discretization of sea-ice dynamics on triangular grids that can straightforwardly be coupled to an ocean model on a triangular grid with Arakawa C-type staggering. The approach is based on a nonconforming finite element framework, namely the Crouzeix-Raviart finite element.

Duality and Dimensionality Reduction Discrete Line Generation Algorithm for a Triangular Grid
ISPRS International Journal of Geo-Information, 2018 Vectors are a key type of geospatial data, and their discretization, which involves solving the problem of generating a discrete line, is particularly important. In this study, we propose a method for constructing a discrete line mathematical model for a
