Recorder Command

Recorders.recorder(tag, filename='Recorder', fileAppend=True, recordfield='DamageLevel', NodesGroupTag=1, MergeSavedFiles=False)

Using this command, a specific result will be recorded for each simulation. The results that can be recorded by this command are listed in the following. The command is fast and it do not take much huge hard disk space. The simulated scenarios will no longer exist and user cannot load them after analysis.

Argument	Type	Description
Tag	int	Unique integer value that will be used for referring to the defined elements or objects.
filename	str	Name of the file that user wants to record data in.
fileAppend	boolean	True says that if the filename exists, add the recorded scenarios to the existing file and false will clear the file if exists.
recordfield	str	A specific Flag that shows which data should be record. In the following, the possible Flags are described.
NodesGroupTag	int	If a property of a NodesGroup is considered in the recordfield to record, the tag of the NodesGroup object should be define here.
MergeSavedFiles	boolean	By setting this option to True, When analysis finished all saved files will be merge into one file with suffix M. Attention that for huge models it may takes so much memory and time and is not recomonded for huge models!

Note

The recordfield existing Flags are as the following table:

Flag	Needs NodesGroupTag	Description
DamageLevel	No	Records the damage level of each plant unit with respect to the tag number (DamageLevel: the level that the plant unit got damage)
NodesGroupIsDamaged	Yes	Records the nodesgroup with tag equal NodesGroupTag is damaged or not (0 for not damaged and 1 for damaged or failed or dead).
FragilityTag	No	Records Fragility tag of each damaged plant unit. Every recorded value is the fragility tag number that cause damage to the corresponding plant unit.
LOC	No	Records loss of containment value of each plant unit.
HazardMag	No	Records the sampled hazard magnitude.
NodesRadiationOverPressure	Yes	Records NodesGroup Radiation and OverPressure values (To prevent creating huge files, the number are recorded with 4 decimals).
NodesRadiationProbit	Yes	Records the NodesGroup Radiation probit value [Probit(Radiation)]
NodesOverPressureProbit	Yes	Records the NodesGroup OverPressure probit value [Probit(OverPressure)]

Example:

The following demonstrates the use of the Recorder command.

Python Code

import opensrane as opr

#To record each simulation DamagedLevel of each plant unit and store in 'RecorderDam' file
opr.Recorders.recorder(tag=1, filename='RecorderDam', fileAppend=False, recordfield='DamageLevel',)

#To record nodes damage probability under radiation using defined probit function and store results is RecorderNodeRad for nodesgroup with tag 2
opr.Recorders.recorder(tag=2, filename='RecorderNodeRad', fileAppend=False, recordfield='NodesRadiationProbit',NodesGroupTag=2)
