Stress‐based Finite Element Methods for Sea Ice Dynamics
Abstract A first‐order system least squares formulation for the sea‐ice dynamics is presented. In addition to the displacement field, the stress tensor is used as a variable.

Summary: | Abstract A first‐order system least squares formulation for the sea‐ice dynamics is presented. In addition to the displacement field, the stress tensor is used as a variable. As finite element spaces, standard conforming piecewise polynomials for the displacement approximation are combined with Raviart‐Thomas elements for the rows in the stress tensor. Computational results for a test problem illustrate the least‐squares approach. |
