       -After compiling the *sphere* binary (see sub-section \ref{subsec:compilation}), the procedure of a creating and handling a simulation is typically arranged in the following order:
       -        \item Setup of particle assemblage, physical properties and conditions using the Python API, described in section \ref{sec:ModelSetup}, page \pageref{sec:ModelSetup}.
       -        \item Execution of *sphere* software, which simulates the particle behavior as a function of time, as a result of the conditions initially specified in the input file. Described in section \ref{sec:Simulation}, page \pageref{sec:Simulation}.
       -        \item Inspection, analysis, interpretation and visualization of *sphere* output in Python. Described in section \ref{sec:DataAnalysis}, page \pageref{sec:DataAnalysis}.
