[06 Aug 2014] You're invited to Let's Talk Meshing, our interactive forum for sharing best practices, methodologies, and application tips on mesh generation for computational fluid dynamics (CFD). A prerecorded video will be posted to YouTube and the Pointwise engineers who made the grid will be available for a live discussion and a Q&A session.
This Let's Talk Meshing video steps you through the meshing process for creating an unstructured grid around a moderately complex geometry. We pay particular attention to solid modeling, uses for scripting, local grid refinement, and creating orthogonal cells in the boundary layers. The geometry was provided by NASA and Gulfstream as a test case for participants in the BANC-III aeroacoustics workshop held in conjunction with the 2014 AIAA Aviation conference in Atlanta, Georgia, in June.
Aeroacoustic simulations require a well resolved flow field, from which pressure fluctuations are used to calculate frequency spectra. Such simulations are most often performed with hybrid RANS/LES or DDES, requiring very smooth transitions in cell volumes and highly resolved surface grids. We will show you how to create such a grid in Pointwise and will demonstrate best practices for handling complex CAD geometries and obtaining a mesh suitable for this type of application.
