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         Fields_Recording_Rate = 1.0D-00 /                       !--- Recording rate (in time unit)
 &Instantaneous_Fields_Listing  Name_of_Field = "U" , Recording_Enabled = .true.  /     !--- Recording of the first velocity component enabled
 &Instantaneous_Fields_Listing  Name_of_Field = "V" , Recording_Enabled = .true.  /     !--- Recording of the second velocity component enabled
 &Instantaneous_Fields_Listing  Name_of_Field = "W" , Recording_Enabled = .false. /     !--- Recording of the Third velocity component disabled
 &Instantaneous_Fields_Listing  Name_of_Field = "T" , Recording_Enabled = .true.  /     !--- Recording Temperature enabled
 &Instantaneous_Fields_Listing  Name_of_Field = "P" , Recording_Enabled = .true.  /     !--- 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>   " , Recording_Enabled = .true.  /   !---- Averaged I-velocity component
 &Statistical_Fields_Listing  Name_of_Field = "<V>   " , Recording_Enabled = .true.  /   !---- Averaged J-velocity component
 &Statistical_Fields_Listing  Name_of_Field = "<P>   " , Recording_Enabled = .true.  /   !---- 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_Recording_Rate                       = 10                                                     /   !--- Recording rate (in time-iteration unit)
 &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
