r3124 r3153 194 194 level interaction with sophisticated graphics primitives. 195 195 See \cite{nielsen2005} for more background on \anuga. 196 197 \chapter{Restrictions and limitations on \anuga} 198 199 Although a powerful and flexible tool for hydrodynamic modelling, \anuga has a 200 number 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 finitedifference 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} 214 196 215 197 216
