# Get VISU engine
myVisu = visu_gui.myVisu

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

# Create submesh presentations

cellEntity = VISU.CELL
nodeEntity = VISU.NODE

mySubMeshes = []

# Create submesh on nodes

# Create submesh on a family (one cell)

# Create submesh on a group (several cells)
