boucle python sous paraview

Version imprimable

Bonjour j'utilise paraview pour visualiser des fichiers de simulation mécanique
Afin d'automatiser l'ouverture et le traitement des images j'ai réalisé un script fonctionnel :

import pvsimple
pvsimple.ShowParaviewView()
# trace generated using paraview version 5.9.0
 
#### import the simple module from the paraview
from pvsimple import *
#### disable automatic camera reset on 'Show'
pvsimple._DisableFirstRenderCameraReset()
i = 0
# create a new 'MED Reader'
bassin0med = MEDReader(registrationName='bassin' + str(i) + '.med', FileName='/media/vesvard211/Crucial X8/resultat_FSI/0.6S/maillage (1)/bassin' + str(i) + '.med')
 
# get animation scene
animationScene1 = GetAnimationScene()
 
# update animation scene based on data timesteps
animationScene1.UpdateAnimationUsingDataTimeSteps()
 
# Properties modified on bassin0med
bassin0med.AllArrays = ['TS0/bassin/ComSup0/Velocity@@][@@P0']
 
# get active view
renderView1 = GetActiveViewOrCreate('RenderView')
 
# show data in view
bassin0medDisplay = Show(bassin0med, renderView1, 'UnstructuredGridRepresentation')
 
# trace defaults for the display properties.
bassin0medDisplay.Representation = 'Surface'
 
# reset view to fit data
renderView1.ResetCamera()
 
# get the material library
materialLibrary1 = GetMaterialLibrary()
 
# update the view to ensure updated data information
renderView1.Update()
 
# set scalar coloring
ColorBy(bassin0medDisplay, ('CELLS', 'Velocity', 'Magnitude'))
 
# rescale color and/or opacity maps used to include current data range
bassin0medDisplay.RescaleTransferFunctionToDataRange(True, False)
 
# show color bar/color legend
bassin0medDisplay.SetScalarBarVisibility(renderView1, True)
 
# get color transfer function/color map for 'Velocity'
velocityLUT = GetColorTransferFunction('Velocity')
 
# get opacity transfer function/opacity map for 'Velocity'
velocityPWF = GetOpacityTransferFunction('Velocity')
 
#### saving camera placements for all active views
 
# current camera placement for renderView1
renderView1.CameraPosition = [0.12, 0.0, 1.7787239526758387]
renderView1.CameraFocalPoint = [0.12, 0.0, 0.1500000000000064]
renderView1.CameraParallelScale = 0.4215447781671621

Mais quand je tente de créer une boucle afin d'ouvrir plusieurs images il ne fonctionne plus

Si quelqu'un à une idée cela m'aiderait grandement

Salut,
Problème d'indentation de ta boucle for ....
17/07/2024, 15h03
umfred

et problème d'utilisation du range => range(start,stop,step) (tu demandes de commencer à 0, de finir à 2 et d'incrémenter de 30 entre chaque itération; conclusion, si la boucle se fait, ce sera une seule fois (pour i =0).

Et "ça ne fonctionne plus" ça ne veut pas dire grand chose:
il y a des messages d'erreur?
ça ne marche pas comme attendu donc ça fait quoi au lieu de faire quoi?
..

Donc commence par corriger le problème du range et l'indentation de ta boucle, et dis nous ensuite ce qui ne fonctionne plus (si ça ne marche toujours pas)

Merci de votre aide
effectivement avec l'indentation et la syntaxe correcte pour le for ça marche :
