Why You Should Be Using Overset Grids

By Nick Wyman, Director, Applied Research, Pointwise, Inc.

The next release of Pointwise features overset grid assembly integration and native support for two assemblers: PEGASUS 5 and Suggar++. Pointwise's new features ease the construction of overset grid systems with visualization and diagnostics of overset grid attributes directly in a mesher.

Glyph Scripting Automates Terrain Meshing for Wind Turbine Siting

By Scott Evetts, Pointwise Intern, Texas A&M University

Texas A&M University student Scott Evetts worked as a Pointwise intern this summer. He had no prior CFD or mesh generation experience, but he was able to accomplish a great deal in three months. Here he describes one of his Glyph scripting projects.

Pointwise Meshes for Computation of Basic States in Boundary Layer Stability

By Travis Kocian, Nicholas Oliviero, Megan Heard, Matthew Tufts, Eduardo Perez, Prof. Helen Reed, Texas A&M University, Aerospace Engineering

Boundary layer transition from laminar to turbulent affects heat transfer, drag, and engine performance, but is still poorly understood. Researchers at Texas A&M are developing computational methods for predicting transition across all speed ranges.

Pointwise Training Includes Overset, New Tools and Techniques

Training at the Pointwise User Group Meeting will include overset meshing, the latest productivity tools, techniques for making high-quality unstructured hexahedral cells using T-Rex (anisotropic tetrahedral extrusion) and an Advanced Structured Gridding short course.
