\section{Discussion and conclusion}
\label{sec:concl}

Recommendations
\begin{itemize}
\item use the LSOR or another implicit solver, because EVP tends to
  have too weak ice, and is much slower for the recommended time step
  choices ($\frac{1}{120}$ of the model time step). Linearization does
  not appear to be an issue for the short time steps used in this
  study ($\Delta{t} = 20\text{\,min}$), and the LSOR-solver converges
  quickly (only a few iterations) at each time step, because the
  forcing changes only slowly within 20\,min.
\item thermodynamics appears to thave the second largest effect (after
  EVP vs.\ LSOR)
\item use a flux limited scheme without explicit diffusion for
  advecting thermodynamic variables
\item use no slip boundary conditions, they make more sense
\item TEM has little effect on the solution, other rheologies that
  differ more from the elliptic yield curve may have bigger effects
\item the effects of \citet{hibler87}'s stress formulation on both ice
  and ocean model need further exploration
\end{itemize}
