At AIAA SciTech: A Framework for Mesh-Geometry Associativity during Mesh Adaptation

Join Pointwise and a co-author from NASA Langley Research Center at AIAA SciTech next month as we present our joint work on a mechanism for providing a CFD flow solver with access to the geometry model for surface mesh adaptation.

The technical paper A Framework for Mesh-Geometry Associativity during Mesh Adaptation is authored by Nick Wyman (Pointwise), Mike Park (NASA), Pat Baker (Pointwise), and John Chawner (Pointwise.)

Abstract

A framework has been developed for describing how a computational mesh is associated to the geometry model it discretizes. The target application of this framework is surface mesh adaptation in a CFD flow solver. The framework, called MeshLink, consists of two components. First, a schema has been defined for describing the one-to-many associativity of a surface mesh to the geometry model entities to which it is attached. Second, a high-level library provides a kernel-agnostic wrapper for providing the necessary geometry queries to an application (e.g., mesher, flow solver). Both the schema and library are provided freely and openly. MeshLink’s ability to support solution mesh adaptation on linear and curved meshes for a high-order flow solution is demonstrated on several test cases relevant to the aerospace and automotive industries.

AIAA SciTech

AIAA’s SciTech Forum next month will be a virtual event with an expanded calendar footprint relative to previous years’ events. SciTech 2021 will be held on 11-15 and 19-21 January.

The paper (according to the conference agenda at the time this post was written) will be presented in session MVCE-07: Meshing Frameworks and Methods on Wed 20 Jan at 2:30 – 3:45.
