Gauss Points

Create Gauss Points presentations on a field of the imported MED file:

import os
from time import sleep

import salome
import SALOMEDS

import VISU
import visu_gui

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

# Get VISU engine
myVisu = visu_gui.myVisu

# Import the file
medFile = os.path.join(datadir,"MedFiles","pointe.med")
myResult = myVisu.ImportFile(medFile)

# Create gauss points for the first timestamp of 'fieldcelldoublevector' field
meshName = 'maa1'
fieldEntity = VISU.CELL
fieldName = 'fieldcelldoublevector'

# Create a Gauss Points presentation of the first type: <b>Results at Gauss Points</b>
myGaussPoints1 = myVisu.GaussPointsOnField(myResult, meshName, fieldEntity, fieldName, 1)

# Set range values (5-50%):
myGaussPoints1.SetMinSize(0.05)
myGaussPoints1.SetMaxSize(0.5)

# Set OpenGL Points as a primitive type
myGaussPoints1.SetPrimitiveType(VISU.GaussPoints.POINT)

# Set the maximum size of points
myGaussPoints1.SetClamp(32)

# Create a Gauss Points presentation of the second type: <b>Gauss Points on Geometry</b>
myGaussPoints2 = myVisu.GaussPointsOnField(myResult, meshName, fieldEntity, fieldName, 1)
myGaussPoints2.SetIsColored(False)

# Set magnification to 200%
myGaussPoints2.SetMagnification(2)

# Set magnification ratio
myGaussPoints2.SetMagnificationIncrement(4)

# Set the size of points
myGaussPoints2.SetGeomSize(0.25)

# Set the color of points
myGaussPoints2.SetColor(SALOMEDS.Color(255, 90, 255))

# Create a Gauss Points presentation of the third type: <b>Gauss Points on Deformed Shape</b>
myGaussPoints3 = myVisu.GaussPointsOnField(myResult, meshName, fieldEntity, fieldName, 1)

# Apply the deformation
myGaussPoints3.SetIsDeformed(True)
myGaussPoints3.SetScaleFactor(0.4)

# Set a geometrical sphere as the primitive type
myGaussPoints3.SetPrimitiveType(VISU.GaussPoints.SPHERE)

# Set sphere resolution
myGaussPoints3.SetResolution(5)

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

# Display the newly created presentations one by one
myViewManager = myVisu.GetViewManager()
myView = myViewManager.Create3DView()

prsList = [myGaussPoints1, myGaussPoints2, myGaussPoints3]
for prs in prsList:
    myView.DisplayOnly(prs)
    myView.FitAll()
    sleep(5)
