Let’s Talk Meshing encourages discussion about various meshing topics through interactive forums, webinars, videos, and live events.
The relative merits of hexahedral versus tetrahedral elements on cell-centered finite volume simulations will be discussed by Dr. John Rhoads, who made the meshes, with special attention given to the sources and mitigation of numerical diffusion. The basic motivation for using hexahedral cells will be explained and several topologies will be introduced that improve the resulting cell quality for realistic, irregularly shaped regions. Dr. Rhoads also will include tips for conceptualizing candidate topologies and explain several tools within Pointwise and some Glyph scripts designed to expedite the process of generating topologies in 2-D and 3-D. Pointwise Senior Engineer Travis Carrigan also will participate in the question-and-answer portion of the event.
Individuals may go to www.pointwise.com/videos to participate. Links to download the scripts used in creating the mesh will be found in the synopsis of the video on YouTube when the forum begins.
Those who want to submit questions can do so in three ways:
