In Pursuit of the Ideal Mesh

Approaches to discretizing models for physics-based simulation have matured considerably over the years with several meshing techniques from which to choose including: multi-block structured, overset, octree, advancing front, and so on. Each of these approaches has its benefits and drawbacks when comparing one with another. Convergence and solution accuracy are evaluated among three mesh configurations of an ONERA M6 wing to help determine whether there exist any advantages of using an unstructured mixed-cell meshing approach over other unstructured advancing front and multi-block structured options.

Impressions From the Third OpenVSP Workshop

The use of computer-aided design (CAD) software is particularly ill-suited during conceptual design where product development tends to be very open-ended and large changes to the geometry definition are typically required in order to explore a vast design space.  Organizations … Continue reading
