Towards Mesh Adaptation with Pointwise Webinar

Towards Mesh Adaptation with Pointwise

[3 October 2017] Despite the evolution of computer processing capability, improving the efficiency of numerical simulations remains an essential issue. Mesh adaptation is a common technique employed to help improve simulation efficiency. In the field of computational fluid dynamics (CFD), unstructured mesh adaptation has been used to substantially reduce the mesh size to reach a desired solution accuracy. Thus, this technique enables significant improvements in processing time, memory requirements, and storage needed.

Furthermore, error estimates have the capability to detect physical phenomena and 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 from directly within Pointwise, modifying and re-projecting points to the underlying geometry during adaptation offers a unique advantage over most off-body mesh adaptation solutions. In this webinar, we introduce adaptation in Pointwise and how this upcoming feature is used to improve upon existing mesh adaptation solutions.

Topics covered include:

  • Incorporating the benefits of mesh adaptation into your simulation workflows
  • Previewing mesh adaptation in an upcoming version of Pointwise
  • 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

point cloud source consisting of more than two-million points

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. +
