2020-12-06 Dear HLPW-4/GMGW-3 TFG member, A new version (V13) of the Official Test Cases Document has been posted to: https://hiliftpw.larc.nasa.gov/Workshop4/testcases.html The V13 document is the same as V12, except that it includes a new (additional) angle of attack for case 2a (20.55 deg.) and 2b (19 deg). Also, the SRS reference in case 3 was removed. A new version of the Mesh Generation Guideline (V11.3) has been posted to: https://hiliftpw.larc.nasa.gov/Workshop4/grids.html The V11.3 document differs from V11.2 only in that it adds a new explanatory paragraph (paragraph 3), and a few other minor changes regarding wall y+ for clarity. The substance of the document is not altered at all.
