 **Simulation_Backup_Rate**
    * Type : Integer value
-   * This variable defines the recording rate, __in time iteration units__ , of the backup files (for instance, when "Simulation_Backup_Rate=1000" a data backup is carried out for all time iteration numbers that are a multiple of 1000).\\ Backup data are dispatched in two files that are named save_var_yyyyy_n.d and save_fld_yyyyy_n.d ('yyyyy' is the subdomain number for simulations based on the MPI domain-decomposition approach, n= 1 or 2 for temporary backup files and n=3 for the backup files created during the last time step of the simulation).

-**Field_Recording_Rate**
+**InstantaneousFields_RecordingStartTime**
    * Type : Real value
-   * This variable defines the recording rate, __in time units__ , of instantaneous fields (for instance, when "Field_Recording_Rate=1.5" an instantaneous field file is created as soon as the time value is a multiple of 1.5).\\ Instantaneous field files are named res_xxxxxxx_yyyyy.d ('yyyyy' is the subdomain number for simulations based on the MPI domain-decomposition approach, 'xxxxxxx' is the file number). The intantaneous fields of the physical quantities are defined with the namelist "Instantaneous_Fields_Listing".
+   * This variable sets the time threshold from which the record of instantaneous fields begins. It must be used along with the next variable "InstantaneousFields_TimeRecordingRate". This value is defined in time unit.
+**InstantaneousFields_TimeRecordingRate**
+   * Type : Real value
+   * This variable defines the recording rate, __in time unit__ , of instantaneous fields. For instance, when "InstantaneousFields_TimeRecordingRate=1.5" a file is created at every 1.5 time unit from the start time provided by the variable "InstantaneousFields_RecordingStartTime".\\
+**InstantaneousFields_StartTimeIterationRecording**
+   * Type : Integer value
+   * This variable sets the time-iteration threshold from which the record of instantaneous fields begins. It must be used along with the next variable "InstantaneousFields_TimeIterationRecordingRate". This value is defined in time-iteration unit (number of time steps).
+**InstantaneousFields_TimeIterationRecordingRate**
+   * Type : Integer value
+   * This variable defines the recording rate, __in time-iteration units__ , of instantaneous fields. For instance, when "InstantaneousFields_TimeIterationRecordingRate=100" a file is created at every 100 time steps from the threshold provided by the variable "InstantaneousFields_StartTimeIterationRecording".\\
+**InstantaneousFields_RecordingReset**
+   * Type : Boolean value
+   * When this variable is set to "true", the ID number of file 'xxxxxxx' is set to zero for the next simulation. This is useful for resetting the file numbering when a simulation is split into several successive parts.
+<note>
+Keep in mind :
+   * Instantaneous field files are named res_xxxxxxx_yyyyy.d. T
+   * 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.
+   *  'xxxxxxx' is the ID number of the file. 'xxxxxxx' is incremented by one for each new file created.
+   * The instantaneous fields of the physical quantities written in each file are defined with the namelist "Instantaneous_Fields_Listing".
+</note>
+<WRAP important>
+ This set of variables must be used in respect of one rule : the user wants to define the recording rate of files either in time unit or in number of time steps (time-ieration unit). In any case, the correct couple of variable must be used.
+   * "InstantaneousFields_RecordingStartTime" and "InstantaneousFields_TimeRecordingRate" in  time unit.
+   * "InstantaneousFields_StartTimeIterationRecording" and "InstantaneousFields_TimeIterationRecordingRate" in number of time steps.
