erro in paraview 3.12
 

Hi,

Trying to calcurate flowrate, this error appears:

Anyone knows what do I have to do for calcurate flowrate?

the error message is here.
AttributeError: 'NoneType' object has no attribute 'GetRange'

I have used python shell as below

#File_Name:FlowRate.py
try: paraview.simple
except: from paraview.simple import *
paraview.simple._DisableFirstRenderCameraReset()

dZ=0.005

Slice1 = Slice( SliceType="Plane" )
Slice1.SliceType.Origin = [0.0, 0.0, hZ]
Slice1.SliceType.Normal = [0.0, 0.0, 1.0]
Slice1.SliceType = "Plane"

ExtractSelection1 = ExtractSelection()

p1=[-0.02, 0.02, hZ+dZ, 1.0]

Flow_Rate_Uz=IntegrateVariables1.CellData[4].GetRange(2)[0]
#IntegrateVariables1.CellData[:]

print 'Flow_Rate_Uz :',Flow_Rate_Uz,'[m/s]'
