PowerData

Power results generated by the Feko Solver.

Example

app = pf.GetApplication()
app:NewProject()
app:OpenFile(FEKO_HOME..[[/shared/Resources/Automation/startup.fek]])

    -- Retrieve the 'PowerData' called 'Power'

powerData = app.Models[1].Configurations[1].Power["Power"]

    -- Manipulate the power data. See 'DataSet' for faster and more comprehensive options
    
dataSet = powerData:GetDataSet(51)
print(dataSet) -- Describes the structure of the data
inspect(dataSet) -- Gives a list of the data set contents

    -- Find the frequency start and end values

frequencyAxis = dataSet.Axes["Frequency"]
frequencyStartValue = frequencyAxis:ValueAt(1)
frequencyEndValue = frequencyAxis:ValueAt(#frequencyAxis)

    -- Scale the power values

scale = 2
for freqIndex = 1, #dataSet.Axes["Frequency"] do
    indexedValue = dataSet[freqIndex]
    indexedValue.ActivePower = indexedValue.ActivePower * scale
end

    -- Store the manipulated data 
    
scaledPower = dataSet:StoreData(pf.Enums.StoredDataTypeEnum.Power)

    -- Compare the original power to the manipulated power
    
graph = app.CartesianGraphs:Add()
powerTrace1 = graph.Traces:Add(powerData)
powerTrace1.Quantity.Type = pf.Enums.PowerQuantityTypeEnum.ActivePower
powerTrace2 = graph.Traces:Add(scaledPower)
powerTrace2.Quantity.Type = pf.Enums.PowerQuantityTypeEnum.ActivePower

Inheritance

The PowerData object is derived from the ResultData object.

Usage locations

The PowerData object can be accessed from the following locations:

Property List

Configuration
The result data's solution configuration in the model. (Read only SolutionConfiguration)
ContinuousFrequencyAxis
Continuous frequency axis exists. (Read only boolean)
DataSetAvailable
Valid result data exist. (Read only boolean)
Label
The object label. (Read/Write string)
Type
The object type string. (Read only string)

Method List

GetDataSet ()
