Deformed Shape and Scalar Map

Create Deformed Shape and Scalar Map presentation on the field of the imported MED file:

import os

import salome

import VISU
import visu_gui

# The directory containing MED files
datadir = os.getenv("DATA_DIR")

# Get VISU engine
myVisu = visu_gui.myVisu

# Import a MED file
medFile = os.path.join(datadir,"MedFiles","fra.med")
myResult = myVisu.ImportFile(medFile)

# Create a deformed shape and a scalar map for the first timestamp of 'VITESSE' field
meshName = 'LE VOLUME'
fieldEntity = VISU.NODE
fieldName = 'VITESSE'
myDefShapeScalarMap = myVisu.DeformedShapeAndScalarMapOnField(myResult, meshName, fieldEntity, fieldName, 1)

# Set the scale
myDefShapeScalarMap.SetScale(0.25)

# Set 'TAUX_DE_VIDE' as a scalar field, use the first timestamp
fieldName = 'TAUX_DE_VIDE'
myDefShapeScalarMap.SetScalarField(VISU.NODE, fieldName, 1)

# Update the object browser
salome.sg.updateObjBrowser(1)

# Display the newly created presentation
myViewManager = myVisu.GetViewManager()
myView = myViewManager.Create3DView()

myView.DisplayOnly(myDefShapeScalarMap)
myView.FitAll()
