CFD Workshop on Geometry Generation and Meshing Techniques
This workshop focused on the use of geometry modeling and mesh generation techniques in Computational Fluid Dynamics (CFD) simulations. Participants discussed key questions, findings, lessons learned, supporting evidence, and future plans relating to geometry manipulation, mesh quality, and the impact on simulation results.

Future Plans What elements of current KQs need further investigation to answer? What new KQs are being proposed and why? What additional CFD or test data is required for support the KQs? What additional help is required from the organizing committee to maximum learning? 3rd Geometry and Mesh Generation Workshop 4th CFD High Lift Prediction Workshop 6 January 2022 | San Diego, CA
Geometry Modeling How many participants used committee-provided geometry to create their own meshes? How many TFG participants modified/altered geometry prior to creating meshes? In which areas? In what way was the geometry modified? Can they quantify how the change impacted the meshing process? Reduced time to mesh? Valid vs invalid mesh? Improved a priori mesh quality metric by a specific amount? 3rd Geometry and Mesh Generation Workshop 4th CFD High Lift Prediction Workshop 7 January 2022 | San Diego, CA
Mesh Generation How many participants have used committee provided meshes? Which levels did they run? How many participants have created their own meshes? Did they follow the meshing guidelines? If not, which guidelines did they deviate from and why? Did they run a simulation before and after the changes? If so what was the impact on their simulations in terms of accuracy and/or convergence? How has mesh quality and validity been quantitatively assessed? Were there trends in metric thresholds across participants? Which areas of the geometry have been the most problematic to mesh? Has remeshing been necessary? If so, where, how, and why? 3rd Geometry and Mesh Generation Workshop 4th CFD High Lift Prediction Workshop 8 January 2022 | San Diego, CA
