[Paraview] vtkPVTrivialProducer issues

[Utkarsh Ayachit]

Here's a modified version of the script, using the updated python
scripting style (since ParaView 3.6)


from paraview.simple import *
from paraview.simple import servermanager as sm
from paraview import vtk

# Set the pvpython path
INPUTFILE="test.vtu"
OUTPUTFILE="tested.vtu"

# create a reader
reader=XMLUnstructuredGridReader(FileName=INPUTFILE)

# get the data i.e moves data from the server to the client
data=sm.Fetch(reader)

tp=TrivialProducer()
obj=tp.GetClientSideObject()
obj.SetOutput(data)

writer=XMLUnstructuredGridWriter(DataMode=2,FileName=OUTPUTFILE)
writer.UpdatePipeline()
