Turbomachinery tip gaps, aircraft wing slats and flaps, and small internal flow passages are just a small subset of the geometries with surfaces in proximity that present challenges for constructing a high-quality volume mesh. Often these surfaces have very different mesh resolution requirements, and this can necessitate a large jump in volume-element size. As a result, highly stretched or skewed elements can be created between the two surfaces and this has a negative impact on mesh quality and ultimately simulation solution accuracy and convergence. In this video, we demonstrate how to effectively use surface mesh adaptation to overcome these challenges and improve overall mesh quality.
In this video, discover how to:
- Effectively use surface mesh adaptation to improve volume mesh quality.
- Adapt grid curves to achieve a smooth, fully adapted surface mesh.
- Select grid entities to act as sources for surface mesh adaptation.
Pointwise, Inc. is solving the top problem facing computational fluid dynamics (CFD) today – reliably generating high-fidelity meshes. The company's Pointwise software generates structured, unstructured, overset and hybrid meshes; interfaces with CFD solvers such as ANSYS FLUENT® and CFX®, STAR-CCM+®, OpenFOAM®, and SU2 as well as many neutral formats, such as CGNS; runs on Windows, Linux, and Mac, and has a scripting language, Glyph, that can automate CFD meshing. Manufacturing firms and research organizations worldwide have relied on Pointwise as their complete CFD preprocessing solution since 1994. www.pointwise.com
