2021-06-08 Dear HLPW-4/GMGW-3 TFG member, The HLPW/GMGW committee and TFG leaders are now preparing overviews for the Workshop Progress Meeting on July 15-16, 2021. Please feel free to continue with your investigations. However, DO NOT send in any more updates... we are going to discuss only the data that we received prior to June 7. One way you can help: If you have made any of your own meshes for HLPW-4, please fill out the following form: https://hiliftpw.larc.nasa.gov/Workshop4/GWGW-3-Participant-Questionnaire_rev7.xlsx found on https://hiliftpw.larc.nasa.gov/Workshop4/grids.html and email it in by June 21. We want to learn more about your meshing experiences for this complex configuration. Finally, note that the final HLPW-4/GMGW-3 workshop is now officially set for Friday January 7, 2022, in San Diego CA (associated with AIAA SciTech 2022).
