+\subsection{Macroscopic cross sections examples}\label{sect:ExMACROLIB}
+
+The sample test cases we will consider here use the \moc{MAC:} module to enter
+macroscopic cross sections directly into DRAGON. They are numbered successively
+from \tst(TCM01) to \tst(TCM08).
+
+\subsubsection{\tst(TCM01) -- Annular region}
+

+\parbox{16cm}{\caption{Geometry for test case \tst(TCM01) for an annular cell with
+macroscopic cross sections.}\label{fig:TCM01}}    
+\end{center}  
+\end{figure}
+
+This sample input is used to analyze the annular cell presented in \Fig{TCM01}.
+It uses two-groups macroscopic cross sections provided directly by the user. One
+type of solution is provided here, one with a complete collision probability
+calculation (\moc{SYBILT:}). Note that for the second flux calculation the
+initial flux distribution is taken from the existing \dds{fluxunk} structure
+which already contains the flux distribution from the
+\moc{SYBILT:} calculation.

+\subsubsection{\tst(TCM02) -- The Stankovski test case.}
+
+\begin{figure}[h!]  
+\begin{center} 
+\epsfxsize=10cm \centerline{ \epsffile{GTCM02.eps}}
+\parbox{14cm}{\caption{Geometry for test case \tst(TCM02).}\label{fig:TCM02}}    
+\end{center}    \end{figure}
+
+This test case represents a one group calculation of a $7\times 7$ PWR assembly.
+The reaction rates obtained from DRAGON can be compared with those obtained
+using the MARSYAS code.\cite{DragonPIJS2,DragonPIJS3,Stankovski} The
+corresponding geometry is shown in \Fig{TCM02} where the cell numbers generated
+by DRAGON are shown.

+\subsubsection{\tst(TCM03) -- Watanabe and Maynard problem with a void region.}
+
+\begin{figure}[h!]  
+\begin{center}

+\parbox{14cm}{\caption{Geometry for test case \tst(TCM03).}
+\label{fig:TCM03}}     \end{center}    \end{figure}
+
+This test case is a one group problem with a central void region. This benchmark
+was first proposed by  Watanabe and Maynard. Akroyd and Riyait used it to
+analyze the performance of various codes.\cite{DragonPIJS2,DragonPIJS3,Akroyd}

+\parbox{14cm}{\caption{Geometry of the CANDU-6 supercell with stainless steel
+rods.}\label{fig:TCM04}}   
+\end{center}  
+\end{figure}
+
+This test case represents a two group calculation of incremental cross sections
+resulting from  the insertion of stainless steel adjuster rods in a CANDU-6
+supercell.

+
+\subsubsection{\tst(TCM05) -- Comparison of leakage models}
+
+This test presents various homogeneous and heterogeneous leakage models on a
+simple cell.
+
+\listing{TCM05.x2m}
+
+\subsubsection{\tst(TCM06) -- Buckling search without fission source}
+
+This test is for an homogeneous water cell. A buckling eigenvalue problem is
+solved in the abscence of fission source for the neutron flux distribution
+inside this cell.
+
+\listing{TCM06.x2m}
+
+\subsubsection{\tst(TCM07) -- Test of boundary conditions}
+
+This test is for a 2--D Cartesian cell with refelctive and void boundary
+conditions.
+
+\listing{TCM07.x2m}
+
+\subsubsection{\tst(TCM08) -- Fixed source problem with fission}
+
+This test is for a 2--D Cartesian cell which contains both a fission and a
+fixed source.
+
+\listing{TCM08.x2m}
+ 
+\subsubsection{\tst(TCM09) -- Solution of a 2-D fission source problem using \moc{MCCGT:}}\label{sect:ExTCM09}
+
+This test case is for a $3\times 3$ Cartesian assembly in 2-D similar to TCM03. It is
+solved using the method of cyclic characteristics.
+
+\listing{TCM09.x2m}

+\subsubsection{\tst(TCM10) -- Solution of a 2-D fixed source problem using \moc{MCCGT:}}\label{sect:ExTCM10}
+
+This test case is for a 2--D Cartesian assembly that contains a fixed source. It is solved
+using the method of cyclic characteristics.

+
+This test case is for a $4\times 4$ Cartesian assembly in 2-D. It is solved using the
+method of cyclic characteristics and the method of collision probabilities using specular
+(mirror like) boundary conditions.

+module}\label{sect:ExTCM12}
