I want to export the below information as a csv file directly from Mechanical via scripting.
1. Convection load Name
2. Film Coefficient
3. Film Coefficient unit
4. Ambient Temperature
5. Ambient Temperature unit

    You can paste the below script in Mechanical scripting console to export all the convection loads corresponding to a thermal analysis (assumption --> this analysis is first in the tree. Please edit the index in DataModel.AnalysisList[i] to access other analyses)

    import os

#Provide the name of the CSV file
fileName = 'Convection_Data.csv'
#Select Analysis by Id
analysis = DataModel.AnalysisList[0]

#Function to write a CSV file from the gathered data
def writeCSV(t1,fileName):
    ExtAPI.Log.WriteMessage('my File name ' + fileName)
    with open(fileName , 'w') as f:
        for line in t1:
            for col in line:
                #For Non-German
                f.write(str(col) + ', ')
                #For German OS 
                #f.write(str(col).replace('.',',') + '; ')
            f.write('\n')

#Find the user files directory for saving the data
UserDir = r"D:\Cases\26832"
saveName = os.path.join(UserDir,fileName)
first_solution = analysis.Solution
solver_data = first_solution.SolverData
allConvections = DataModel.GetObjectsByType(DataModelObjectCategory.Convection)
allData = []
for convectionObj in allConvections:
    convName = convectionObj.Name
    lastIndexConv = convectionObj.FilmCoefficient.Output.DiscreteValueCount-1
    lastIndexAT = convectionObj.AmbientTemperature.Output.DiscreteValueCount-1
    convFCVal = convectionObj.FilmCoefficient.Output.GetDiscreteValue(lastIndexConv).Value
    convFCUnit = convectionObj.FilmCoefficient.Output.GetDiscreteValue(lastIndexConv).Unit
    convATVal = convectionObj.AmbientTemperature.Output.GetDiscreteValue(lastIndexAT).Value
    convATUnit = convectionObj.AmbientTemperature.Output.GetDiscreteValue(lastIndexAT).Unit
    allData.append([convName, convFCVal, convFCUnit, convATVal, convATUnit])

writeCSV(allData,saveName)
