     197\chapter{Restrictions and limitations on \anuga}
     198
     199Although a powerful and flexible tool for hydrodynamic modelling, \anuga has a
     200number of limitations that any potential user need to be aware of. They are
     201
     202\begin{itemize}
     203  \item The mathematical model is the 2D shallow water wave equation.
     204  As such it cannot resolve vertical convection and consequently not breaking
     205  waves or 3D turbulence (e.g.\ vorticity).
     206  \item The finite volume is a very robust and flexible numerical technique,
     207  but it is not the fastest method around. If the geometry is sufficiently
     208  simple and if there is no need for wetting or drying, a finite-difference
     209  method may be able to solve the problem faster than \anuga.
     210  %\item Mesh resolutions near coastlines with steep gradients need to be...   
     211  \item Frictional resistance is implemented using Manning's formula, but
     212  \anuga has not yet been validated in regard to bottom roughness
     213\end{itemize}
