DESCRIPTION:Timothy Williams\, Pierre Rampal\, Einar
Olason\, Syvain Bouillon and Abdoulaye Samake
The neXtSIM (neXt generation Sea Ice Model
) sea ice model runs the Maxwell-EB rheology solve
d with finite element methods on a triangular mesh
. It also has thermodynamic effects and a slab oce
an included beneath\, as well as wave-ice interact
ions (ice break-up by waves\, ice drift due to the
wave radiation stress).
An ALE (Arbitrary
Lagrangian/Eulerian) scheme has now been implemen
ted in neXtSIM\, so that the mesh is usually movin
g as time goes on. As part of an investigation abo
ut the best strategy for coupling the waves-in-ice
module (WIM) to neXtSIM\, the WIM may now be run
on the neXtSIM mesh.
In this talk we give a
n overview of both neXtSIM and the WIM\, and also
some results comparing the different coupling stra
tegies for the WIM.
