The automatic O-Grid option in ICEM CFD Hexa is one the most powerful
features. The user only has to build the H-Mesh topology and the O-Mesh
topology can be added automatically.
You can easily scale the overall ogrid thickness, the thickness at any particular point, or the near wall mesh spacing or distribution. Ogrids can be easily place inside or around complex bodies.
OGRIDS are ideal for capturing boundary layer phenomenon.
