\chapter{Open Project}\label{sec:USOpenProject}

To be able to open a project, the user must be able to build a project, to save it and to open it.

\section{Building a project}\label{sec:BuildingProject}
The user can define a project by defining different sources, see \autoref{sec:USDataFormat} and \autoref{sec:USDataCombi}

\section{Saving a project} \label{sec:SavingProject}
The project can be saved at a location defined by the user.

\section{Opening a project}\label{sec:OpeningProject}
The user must be able to open an excisting project. When calculations were made, also the calculation results must be shown.
When a project is calculated in a previous version of DAM (i.e. DAM 18.1 instead of 19.1), the calculations must not be shown because the calculations can be outdated due to newer versions of used kernels.
