The Ogrid creation capability is simply the modification of a single block or blocks to a 5 sub-block topology as shown below. There are several variations of the basic Ogrid generation technique; the Ogrid shown below is created entirely inside the selected block.

Figure 29: Initial block, Block with Ogrid, Ogrid with Add Face

Using the Add face feature, an Ogrid can be created such that the Ogrid passes through the selected block faces. In Figure 29: Initial block, Block with Ogrid, Ogrid with Add Face, the Add face feature was used on the last block to include one face on the block prior to generating the Ogrid.
