Hello everyone, I am facing a problem with updating my animation scene. I am trying iterate over a number of frames and exporting csv file files but I am just getting csv files with same values, which means the spreadsheet doesnt update. I would be really thankful if someone can help because I am in trouble. Here is the part of my code where the problem is :
```python
particle_tracer.ForceReinjectionEveryNSteps = 0
input_directory= path_for_video
frames=from_sec_to_timesteps(pvd_path, sim_time)
animation_scene = GetAnimationScene()
animation_scene.NumberOfFrames = frames
spreadSheetView1 = CreateView('SpreadSheetView')
i = 0
for frame in range(frames):
temporalParticlesToPathlines1 = TemporalParticlesToPathlines(
registrationName='TemporalParticlesToPathlines1',
Input=calculator1, Selection=None)
temporalParticlesToPathlines1.MaskPoints = 1
temporalParticlesToPathlines1.MaxTrackLength = 10000
temporalParticlesToPathlines1.MaxStepDistance = [1000.0, 1000.0, 1000.0]
Show(temporalParticlesToPathlines1, spreadSheetView1, 'SpreadSheetRepresentation')
spreadSheetView1.HiddenColumnLabels = ['Point ID', 'AngularVelocity', 'ErrorCode', 'InjectedPointId',
'InjectionStepId', 'NormShearRate [1/s]',
'ParticleAge', 'ParticleSourceId', 'Points', 'Points_Magnitude',
'Pressure [bar]', 'Rotation', 'Screw', 'Shell', 'Temperature [C]',
'TrackLength', 'TrailId', 'Velocity [m/s]',
'Velocity [m/s]_Magnitude',
'Viscosity [Pa s]',
'Vorticity', 'vel', 'vel_Magnitude', 'Block Number']
input_file_path = os.path.join(input_directory, f'Timestep_{i}.csv')
ExportView(input_file_path, view=spreadSheetView1, RealNumberNotation='Fixed')
animation_scene.GoToNext()
animation_scene.UpdateAnimationUsingDataTimeSteps()
i += 1
```

I think you should use the `CSV` extractor instead, and then call `Save Extracts` in your script, instead of using animation scene, spreadsheet and a loop.
### Rationale
Extractor are writers that will be called at each timesteps when you call `Save Extracts`.
ParaView pipeline should mainly not be created in a temporal loop. It is intended to be created once, then executed for each timestep.
Spreadsheet is a view, not a data type. So it is not required to save csv files.
You may choose the arrays to write with `Pass Arrays` filter before the extractor.
