Hello everyone!

I'm trying to write a python scritp in order to animate a slice in paraview. But I have a problem, when I run the script it returns 'slice object has no len()'. The problem is in these lines:
Code:
cue = KeyFrameAnimationCue()
SetActiveSource(slice1)
cue.AnimatedElement= GetActiveSource()
cue.AnimatedPropertyName = 'SliceOffsetValues'
AnimationScene1.Cues=[cue]
I don't know which is failing.

Thanks a lot.

Ok, I have not been successful. Here is the complete script.
Can someone help me please?

Code:
from paraview.simple import *
paraview.simple._DisableFirstRenderCameraReset()

#Abre el archivo de OpenFOAM
foamFile = OpenFOAMReader(FileName = "spalartAllmaras.OpenFOAM")
timeSteps = foamFile.TimestepValues #Time steps en forma de array

#Crea la vista y la camara 
view1=CreateRenderView() #Crea una vista
view1.ViewSize = [800, 700] #Tamano de la vista
view1.CameraPosition = (0.4,-3.5,0.44) #Posicion de la camara 
view1.CameraFocalPoint = (0.4,0,0.44)  #Punto al que enfoca la camara
view1.CameraViewUp = (0,0,1) #Vector unitario para decidir que direccion se muestra hacia arriba
view1.CameraViewAngle = 30 #Angulo de la camara

#Slice
slice1=Slice(foamFile)
slice1.SliceType.Normal=(0,1,0)
slice1.SliceType.Origin = (0.4, 0, 0.44)

#Tiempo y vector velocidad.
view1.ViewTime = timeSteps[20]
annTime = AnnotateTimeFilter(foamFile)
Show(annTime)
annTime.Format="Time Step: %.f"

sliceDisplay = Show(slice1,view1)
sliceDisplay.ColorArrayName = ['POINTS', '']
ColorBy(sliceDisplay, ('POINTS', 'U'))
sliceDisplay.RescaleTransferFunctionToDataRange(True)
velLUT = GetColorTransferFunction('U')
velPWF = GetOpacityTransferFunction('U')

# RANGOS: Mag(0,6.8) X(-2,6.7), Y(-0.05,0.1), Z(-1.7,4.1)
velLUT.VectorMode='Magnitude'
velLUT.VectorComponent=2 #[Mag,U,V,W]
velLUT.RGBPoints = [0, 0, 0, 1, 6.8, 1, 0, 0] #Punto y color rgb

#Color bar
scalarBar = GetScalarBar(velLUT, view1)
scalarBar.Orientation='Horizontal'
scalarBar.Position = [0.3, 0.15]
scalarBar.Title="Velocidad" #Titulo
scalarBar.ComponentTitle="Magnitud" #Componente
scalarBar.LabelFormat="%.2f" #Formato de la escala
scalarBar.RangeLabelFormat="%.2f" #Formato del rango


#Animacion
AnimationScene1 = GetAnimationScene()
AnimationScene1.PlayMode = 'Sequence'
AnimationScene1.NumberOfFrames = 150

cue = KeyFrameAnimationCue() # < ---- ----- ---- ---- NO VA
SetActiveSource(slice1)
cue.AnimatedElement = GetActiveSource()
cue.AnimatedPropertyName = 'SliceOffsetValues'
AnimationScene1.Cues=[cue]

keyFrame0 = CompositeKeyFrame()
keyFrame0.Interpolation = 'Ramp'
keyFrame0.KeyTime = 0
keyFrame0.KeyValues= [-0.1]

keyFrame1 = CompositeKeyFrame()
keyFrame0.KeyTime = 100
keyFrame0.KeyValues= [0.1]

cue.KeyFrames = [keyFrame0, keyFrame1]

AnimationScene1.Play()

Hi,
an example of a Python script is here: https://www.researchgate.net/publica...t_and_ParaVIEW

Have Fun!

Thank you for the reply, but this is not what I am looking for. There is not paraview scripting with paraview.simple python module.

Can someone tell me about some pvpyhon books? I have already read the paraview guide, but it does not teach how make a animated slice.
