\subsection{Method for avoiding mesh interfaces in blockage outline view}
12461247

1248+
FDS splits a blockage into separate parts, one part for each mesh. As a result when Smokeview draws blockages as outlines it draws extra lines where blockages intersect mesh interfaces. The following procedure can be used to eliminate these extra lines for a case named say casename.fds .
1249+
1250+
\begin{enumerate}
1251+
\item Create a one mesh version of casename.fds case . Name it casename\_single.fds (or anything different than casename.fds) . Set T\_END to 0.0 and CHID to casename\_single~.
1252+
\item After running casename\_single.fds with fds, rename the generated casename\_single.smv file casename.smo~.
1253+
\item Run smokeview casename~.
1254+
\item Select the Show/Hide>Geometry>Obstacles>Outline only menu item to view the blockages as outlines.
1255+
\item press the `q' key to toggle between viewing blockages split at mesh boundaries (how fds handles them) and how blockages are defined in the input file.
1256+
\end{enumerate}
1257+
1258+
Figure \ref{fig:outlinehack} shows an example where blockages are drawn as specified in the input file and drawn split at mesh interfaces.
