FOR IMMEDIATE RELEASE
Pointwise Forum to Focus on Complex Geometries, Very Large Grids
FORT WORTH, TX (23 July 2014) – Pointwise will host a Let's Talk Meshing interactive forum at 10 a.m. CDT (GMT -5) on 6 August to discuss tips for handling complex geometries and very large grids. 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 question-and-answer session.
The video demonstrates each step of the meshing process for creating an unstructured grid around a moderately complex geometry, paying 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. The video will demonstrate how to create such a grid in Pointwise and best practices for handling complex CAD geometries and obtaining a mesh suitable for this type of application.
Individuals may go to www.pointwise.com/videos to participate. Links to the scripts used in creating the mesh will be in the synopsis of the video on YouTube when the forum begins.
