Documentation du code de simulation numérique SUNFLUIDH

Here we show an example of usual data acquisition :

• Instantaneous fields
• Statistical fields
• Time series from probes located at specific positions

The various parameters related to each type of output data are originally splitted by topic in the appropriate namelist. For a sake of clarity, they are directly regrouped for each type of output data as shown here :

For instantaneous fields

 &Field_Recording_Setup         Precision_On_Instantaneous_Fields= 2 /                  !--- option value for writing results in double precision (1 = single precision)
 
 &Simulation_Management
     InstantaneousFields_RecordingReset=.false.      ,    !--- Reset to zero the file number ID
     InstantaneousFields_TimeRecordingRate= 5.0E-01  ,    !--- Recording rate in "time unit"
     InstantaneousFields_RecordingStartTime= 1.D-00  ,    !--- Threshold from which the recording begins (used with InstantaneousFields_TimeRecordingRate only)
  !  InstantaneousFields_TimeIterationRecordingRate= 10 , !--- Recording rate in "time-step iteration unit (number of time steps)"
  !  InstantaneousFields_StartTimeIterationRecording= 70  !--- Threshold from which the recording starts (used with InstantaneousFields_TimeIterationRecordingRate only)
 /
 &Instantaneous_Fields_Listing  Name_of_Field = "U"  /     !--- Recording of the first velocity component enabled
 &Instantaneous_Fields_Listing  Name_of_Field = "V"  /     !--- Recording of the second velocity component enabled
 &Instantaneous_Fields_Listing  Name_of_Field = "W"  /     !--- Recording of the Third velocity component disabled
 &Instantaneous_Fields_Listing  Name_of_Field = "T"  /     !--- Recording Temperature enabled
 &Instantaneous_Fields_Listing  Name_of_Field = "P"  /     !--- Recording Pressure enabled
 

For statistical fields

 &Simulation_Management Start_Time_For_Statistics= 1.D+2               ,          !--- Start time for computing the statistical fields
                        Time_Range_Statistic_Calculation = 1.D+00      /          !--- time range over which the statistical field computation is performed. 
                                                                                        When it has been covered, the results are recorded and a new statistical computation starts again                 
 &Field_Recording_Setup      Precision_On_Statistical_Fields= 2 ,                 !--- option value for writing results in double precision (1 = single precision)
                             Time_Statistics_Enabled= .true.    ,                 !--- time statistics  are performed (true) - classical statistics (false)
                             Sample_Rate_For_Statistics= 1      ,                 !--- Sample rate (in time iteration unit)
                             Statistic_Space_Average_Type= "NO_SPACE_AVERAGE" /   !--- option on spatial averaged fields
 &Statistical_Fields_Listing  Name_of_Field = "<U>   " /   !---- Averaged I-velocity component
 &Statistical_Fields_Listing  Name_of_Field = "<V>   " /   !---- Averaged J-velocity component
 &Statistical_Fields_Listing  Name_of_Field = "<P>   " /   !---- Averaged pressure

For time-series from probes

                                                                       U    , V     , W      , T      , P     , RHO
 &Probe_Quantities_Enabled  Temporal_Series_For_Quantity_Enabled(:)= .true. , .true., .false., .false., .true., .false.    /    !--- Selection of physical quantities
 &Simulation_Management  
          Probe_TimeIterationRecordingRate= 2 ,   !--- Recording rate in "time-step iteration unit (number of time steps)"
          Probe_RecordingReset=.false. ,          !--- if True, Time series are written in new files (with the same name), previous data are removed
          Probe_StartTimeIterationRecording= 20   !--- Threshold from which the recording starts
 /
 &Probe_Location  Xi= 2.0 , Xj= 1.5 , Xk= 0.0 /       !---coordinates of probe 1
 &Probe_Location  Xi= 3.0 , Xj= 1.0 , Xk= 0.0 /       !---coordinates of probe 2
