+\section{Contents of a \dir{fview} data structure}\label{sect:dfview}
+
+This directory contains information generated by the \moc{VAL:} module used to interpolate the diffusion flux computed for Cartesian geometries. The following options of calculations are currently implemented:
+\begin{itemize}
+\item 3D geometries tracked with \moc{TRIVAT:} using \moc{PRIM} (aka, variational collocation) method
+\item 3D geometries tracked with \moc{TRIVAT:} using \moc{DUAL} (aka, Raviart-Thomas) method
+\item 3D geometries tracked with \moc{TRIVAT:} using \moc{MCFD} (aka, nodal collocation) method
+\end{itemize}
+
+\subsection{The state-vector content}\label{sect:fviewstate}
+
+\begin{itemize}
+
+\item The total number of energy group $N_{g} = \mathcal{S}_{1}$
+
+\item The number of mesh along X direction $N_{x} = \mathcal{S}_{2}$
+
+\item The number of mesh along Y direction $N_{y} = \mathcal{S}_{3}$
+
+\item The number of mesh along Z direction $N_{z} = \mathcal{S}_{4}$
+
+\end{itemize}
+
+\subsection{The main \dir{fview} directory}\label{sect:fviewdir}
+
+\begin{DescriptionEnregistrement}{Records and sub-directories
