Simulation parameters
The file controlDict in the system directory contains the information necessary to start a simulation like:
Duration (startTime and endTime)
Calculation time step deltaT
Results writing frequency writeInterval

// ************************************************************************* //Fondamental :
The fvSolution and fvSchemes contains important information about numerical schemes that goes beyond the scope of this workshop. The case studies here are already configured with the working configuration but remind that this a fundamental step of a CFD simulation! More details here [pdf][1].
