Output data

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
