Video Tutorial Shows O-H Topology Step-by-Step

This 11-minute video reveals the answer to one of our most frequently asked questions: how to create a circular structured grid. It introduces how to use an H grid and an O-H grid (or “Butterfly”) topology to produce circular structured grids. We walk you through the steps of creating the underlying connector layout, then show you the benefits of using an O-H grid topology over an H grid topology for circular cross-sections.

See it for yourself at our website's DIY Training page.
