    18101810computed in the model or whether they should be reduced to one
    18111811value per vertex using averaging.

     1813Triangles stored in the sww file can be discontinuous reflecting
     1814the internal representation of the finite-volume scheme
     1815(this is a feature allowing for arbitrary steepness).
     1816However, for visual purposes and also for use with \code{Field\_boundary}
     1817(and \code{File\_boundary}) it is often desirable to store triangles
     1818with values at each vertex point as the average of the potentially
     1819discontinuous numbers found at vertices of different triangles sharing the
     1820same vertex location. 
     1821 
     1822Storing one way or the other is controlled in ANUGA through the method
     1823\code{domain.store\_vertices\_uniquely}. Options are
     1824\begin{itemize}
     1825  \item \code{domain.store\_vertices\_uniquely(True)}: Allow discontinuities in the sww file
     1826  \item \code{domain.store\_vertices\_uniquely(False)}: (Default).
     1827  Average values
     1828  to ensure continuity in sww file. The latter also makes for smaller
     1829  sww files.
     1830\end{itemize}
