AEATECHNOLOG ENGINEERING SOFTWARE Regions Different graphic objects accept different region types. For example contour, fringe, and relief operate only on 2-D(planar) regions, either physical or nodal graph operates on 1-D(line)regions, either physical or nodal grid, vectoroperate on 1-D, 2-D and 3-D nodal regions planar physIcal regions etc 10-7 CFX-4.3V4.3.1H CFX-4 Introductory Training (Dec 1999)
