    Below script exports the Max or Min time history as csv for multiple named selections (say T1 and T2) in the analysis solver directory.

    import mech_dpf
import Ans.DataProcessing as dpf
import csv
import os
import time
startTime = time.time()


mech_dpf.setExtAPI(ExtAPI)
analysis = DataModel.AnalysisList[0]

# Specify the file name for Max and Min data
filenameMax = "output_max.csv"
filepath = analysis.WorkingDir
fullpathMax = os.path.join(filepath,filenameMax)

filenameMin = "output_min.csv"
filepath = analysis.WorkingDir
fullpathMin = os.path.join(filepath,filenameMin)

dataSource = dpf.DataSources(analysis.ResultFileName)

time_freq_support = dpf.operators.metadata.time_freq_provider(data_sources = dataSource)
n_sets = time_freq_support.outputs.time_freq_support.GetData().NumberSets
timeScop = dpf.Scoping()
timeScop.Ids = range(1, n_sets + 1)

NamedSelNames = ['T1', 'T2', 'T3', 'T4', 'T5', 'T6', 'T7', 'T8', 'T9', 'T10', 'T11', 'T12', 'T13', 'T14', 'T15', 'T16', 'T17', 'T18', 'T19', 'T20', 'T21', 'T22', 'T23', 'T24', 'T25', 'T26', 'T27', 'T28', 'T29', 'T30', 'T31', 'T32', 'T33', 'T34']
fullDataMax = []
fullDataMin = []
for nsName in NamedSelNames:
    ns_op = dpf.operators.scoping.on_named_selection(data_sources = dataSource, requested_location = 'Nodal', named_selection_name = nsName)
    temp_op = dpf.operators.result.temperature(data_sources = dataSource, time_scoping = timeScop, mesh_scoping = ns_op.outputs.mesh_scoping)
    temp_fc = temp_op.outputs.fields_container.GetData()
    minTemps = []
    maxTemps = []

    min_max_fc_op = dpf.operators.min_max.min_max_fc() # operator instantiation
    min_max_fc_op.inputs.fields_container.Connect(temp_fc)
    minTemps = min_max_fc_op.outputs.field_min.GetData().Data
    maxTemps = min_max_fc_op.outputs.field_max.GetData().Data

    fullDataMax.append(maxTemps)
    fullDataMin.append(minTemps)

fullDataMax = list(zip(*fullDataMax))
fullDataMin = list(zip(*fullDataMin))

# Writing to csv file
with open(fullpathMax, mode='w') as file:
    writer = csv.writer(file, lineterminator='\n')
    writer.writerow(NamedSelNames)
    for row in fullDataMax:
        writer.writerow(row)

with open(fullpathMin, mode='w') as file:
    writer = csv.writer(file, lineterminator='\n')
    writer.writerow(NamedSelNames)
    for row in fullDataMin:
        writer.writerow(row)
endTime = time.time()
TotalTime = endTime - startTime
ExtAPI.Log.WriteMessage("Total Time taken for export is " + str(TotalTime) + " Sec")
