2021-03-03 Dear HLPW-4/GMGW-3 interested person, Many of you have already learned that AIAA is moving the 2021 AIAA Aviation Forum from June to early August 2021, and it will be an all-virtual event. HLPW-4 is currently working out how this announcement will affect our workshop. New plans will be announced in the near future. Updates will be posted to the HLPW-4 website (https://hiliftpw.larc.nasa.gov/index.html). In the meantime, work within the various TFGs is continuing as usual. Note that new meshes are being posted as they become available, to: https://hiliftpw.larc.nasa.gov/Workshop4/grids_downloads.html A new set of Pointwise unstructured committee meshes have recently been posted for the off-nominal flap angle 37/34 (level D only). Unstructured meshes 103 and 104 from ANSA have also recently been made available.
