Abstract

In 2017, AIAA will be conducting its inaugural Geometry and Mesh Generation Workshop (GMGW-1), in conjunction with its High-Lift Prediction Workshop (HiLiftPW- 3). In preparation for these workshops, several authors have submitted candidate meshes for use by the HiLiftPW-3 participants. The GMGW-1 steering committee selected, from amongst the submissions, the baseline meshes that should be used by the HiLiftPW-3 participants. This selection was based upon the meshing guidelines published by the workshop organizers. This paper describes the techniques developed to assess the degree to which each candidate grid adheres to the guidelines. The assessment includes a quantitative assessment of the distance of the surface mesh points to the actual geometry, statistics about the on-body and off-body spacings, and mesh stretching statistics. Simple checks, such as appropriate mesh connectivity and non-negative cell volumes, are also included. We expect that these techniques will be suitable not only for evaluating candidate HiLiftPW-3 meshes, but will suitable for any future AIAA Workshop for which candidate computation meshes are published. Note that the actual assessments were described during the Workshop. This paper concentrates on the tools that have been developed to perform the assessment.
