[Paraview] Threshold filter in python script

[Berk Geveci]

Try this horrible incantation instead:

 tf.SelectInputScalars = ['0', '0', '0', '1', 'GlobalElementId']

In 3.6, this script will be:

from paraview.simple import *

e = ExodusIIReader(FileName='mesh.e')
tf = Threshold(e, ThresholdRange = [10, 10], Scalars = ['CELLS',
'GlobalElementId'])
Show(tf)
Render()
