| Zusammenfassung |
| The Finite-Element Sea Ice Model (FESIM), used as a component of the Finite-Element
Sea ice Ocean Model, is presented. Version 2 includes the
elastic-viscous-plastic (EVP) and viscous-plastic (VP) solvers and employs a
flux corrected transport algorithm to advect the ice and snow mean
thicknesses and concentration. The EVP part also includes a modified approach
proposed recently by Bouillon
et al. (2013), which is
characterized by an improved stability compared to the standard EVP approach.
The model is formulated on unstructured triangular meshes. It assumes a
collocated placement of ice velocities, mean thicknesses and concentration at
mesh vertices, and relies on piecewise-linear (P1) continuous elements.
Simple tests for the modified EVP and VP solvers are presented to show that
they may produce very close results provided the number of iterations is
sufficiently high. |
