Advanced Structured Grid Techniques

[11 Dec 2014] This video focuses on techniques for creating structured hexahedral grids with Pointwise. The relative merits of hexahedral versus tetrahedral elements on cell-centered finite volume simulations will be discussed, with special attention given to the sources and mitigation of numerical diffusion. After establishing the basic motivation for using hexahedral cells, we will introduce several topologies that improve the resulting cell quality for realistic, irregularly shaped regions, including tips for conceptualizing candidate topologies. Also, we will introduce several tools within Pointwise and some Glyph scripts designed to expedite the process of generating topologies in 2-D and 3-D.

Generating structured grid topologies for non-rectangular geometries such as this fillet can be expedited through the use of utility scripts and other tools in Pointwise.
