 \chapter{Calculation settings}\label{sec:USCalcSettings}
+All calculation settings are the same for all dike rings and locations within the project. So there is only one set of calculation settings.
+
 \section{Macrostability}\label{sec:Macrostability}
+In DAM the following piping models can be used:
+\begin{itemize}
+	\item \textit{Bishop}
+	\item \textit{UpliftVan}
+	\item \textit{Bishop-UpliftVan}
+\end{itemize}
+
+Note that for both \textit{Bishop} and \textit{UpliftVan} a brute force search method based on moving grids is offered. 
+For \textit{UpliftVan}, 
+the search method \textit{Bee Swarm} is an alternative option.
+The combi model \textit{Bishop-UpliftVan} always uses the brute force search method for the \textit{Bishop} calculations whereas for the \textit{UpliftVan} a choice can be made between brute force and \textit{Bee Swarm}.
+
+The determination of position the grid(s) must offer automatic positioning next to a user steered method.
+In the latter case, the user defines the dimension of the grid(s) by entering the number of grid points and the distance between the points 
+(in both X- and Z-direction; for both grids when required). 
+ 
+The combi model \textit{Bishop-UpliftVan} performs the calculations as follows. For each calculation that is to be made 
+(a combination of location, scenario, subsoil/surface line and iteration step), first of all a short calculation is performed to determine whether uplift does occur for the given case. 
+If so, an \textit{UpliftVan} calculation is to be performed next to the \textit{Bishop} calculation that is always part of this model.
+If not, only the \textit{Bishop} calculation is done.
+ 
+For each calculation, at least one stix file is written to a calculation folder per model. 
+This (result) stix file hold the input as passed to the \textit{Macro Stability} kernel as well as the resulting slip circle (\textit{Bishop}) or slip plane (\textit{UpliftVan}). 
+This file can be used to replicate the result as obtained using DAM by performing the calculation with \textit{D-Stability}. 
+This of course will only be true when the same version of \textit{Macro Stability} kernel is used by both programs.
+
+Possible second stix = input.
