A point cloud source consisting of more than two-million points was imported into Pointwise using a Glyph script. The target edge lengths assigned to each point were then used to adapt the surface and volume grid in critical regions of the flow field over an ONERA M6 wing.

Pointwise Used to Improve Existing Mesh Adaptation Solutions

FORT WORTH, TX (21 September 2017) – In the webinar, “Towards Mesh Adaptation with Pointwise”, we introduce adaptation in Pointwise and how this feature is used to improve upon existing mesh adaptation solutions.

Mesh adaptation is a common technique employed to help improve engineering simulation efficiency. In the field of computational fluid dynamics (CFD), unstructured mesh adaptation has been used to substantially reduce the mesh size needed to reach a desired solution accuracy. Thus, this technique enables significant improvements in processing time, memory requirements, and storage needed.

Error estimates based on the flow solution can detect physical phenomena and give local target mesh lengths needed to capture their behavior. Meshes are then automatically adapted in critical regions without any a priori knowledge of the solution. However, without access to the underlying CAD data, adaptation is limited only to improving off-body grid resolution. Given that access to CAD is available directly within Pointwise, and added or moved grid points can be reprojected onto the underlying geometry during adaptation, which offers a unique advantage over most off-body mesh adaptation solutions.

Topics covered include:

  • Incorporating the benefits of mesh adaptation into your simulation workflows
  • Using Glyph scripting to import point cloud source objects
  • Applying mesh adaptation to better resolve critical regions of the flow over the ONERA M6 wing

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 and hybrid meshes; interfaces with CFD solvers such as ANSYS FLUENT, 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.
