+===== Split the namelist =====
+<note>
+As the number of data in this namelist can be large and bounded to different types of functionnalities (probes, instananeous fields, statistical quantities, simulation parameters, ...), the full dataset of this namelist can be split into several parts in the input data file. Each part is defined with the same namelist name ("Simulation_Management") but each dataset must be different.

+<note>
+Keep in mind :
+   * For space-averaged field along a specific direction, the files are named spav_Id_dir_xxxxxxx_yyyyy.d.
+   * Id is the ID number of the Slice.
+   * dir specifies the direction of the slice
+   * The number 'yyyyy' stands for the subdomain number on which fields are recorded for simulations based on the MPI domain-decomposition approach. When the domain decomposition approach is not used (just one domain), 'yyyyy=00000' is the default value. This number is not present if the option "Slice_Gathering_Enabled" is set to "true" in the namelist "Field_Recording_Setup" because every fields split over several subdomain are gathered in the same file.
+   *  'xxxxxxx' is the ID number of the file. 'xxxxxxx' is incremented by one for each new file created.
+   * The space-averaged fields written in each file are defined with the namelist "SpaceAveragedSnapshots_Dataset".
