Test Cases for the Third AIAA Sonic Boom Prediction Workshop Version 3, updated 13-JUN-2019 Grids, geometry, data submittal forms, and instructions are available at https://lbpw-ftp.larc.nasa.gov/sbpw3/ The cases and instructions for atmospheric propagation are available in a propagation directory. The required nearfield CFD grids for the 'biconvex' shock-plume interaction are available. The low boom flight model test case is under development The 'axie' case is a repeat from the Second Workshop and should have been submitted with the intent to participate in the nearfield CFD portion of the workshop. The 'propagation/axibody' case is a repeat from the Second Workshop and should have been submitted with the intent to participate in the atmospheric propagation portion of the workshop. Each participant group is required to submit a LastName-info.txt file, see the template on the ftp site. Duplicate the solver information sections if more than one simulation tool is used. Duplicate the case information sections as necessary. Ensure that any data file submitted includes the ModelName, corresponding participant's LastName, and the CaseName in the file name. There is a "data-submittal" directory under each model directory. A README and templates for each form are available in this location. The "data-submittal" directory may also contain scripts and other information to aid data extraction and submittal. For each nearfield CFD case, a minimum of 3 grids in a uniform refinement series must be used if their solver can utilize a grid format provided. This should include the finest grid that the participant has the resources to run and two or more consecutive courser grids. Both inviscid and viscous grids are provided for some cases. The participant may choose to submit either inviscid analysis, viscous analysis, or both. If inviscid and viscous analysis is performed, a minimum of a three grid refinement study using the required grids is required for both inviscid and viscous analysis. The evaluation of multiple schemes, codes, or turbulence models is encouraged. Optional grids are provided for some models in an "optional" directory. Results for the optional grids are requested from participants, but not required. Participants are encouraged to generate their own grids using their best practices. The extent of these generated grids should be large enough to capture the return of the tail portion of the signature to near ambient pressure levels. Adaptive methods are also encouraged. Participants with adaptive grid results should submit a data set (CaseName) for their finest adaptive grid and two or more intermediate grids that are as close to factors of two reduction in degrees of freedom as possible. For example, if your finest adapted grid has n vertices, submit your intermediate grids that are as close to n/2 and n/4 vertices as possible. The grid for any case submitted to the workshop must be submitted with the results by uploading the grid to the FTP server. Acceptable grid formats are CGNS, AFLR3 ugrid, and VGRID cogsg. If you need a description of the formats or are not able to produce one of these formats, please contact the workshop committee for assistance. SFTP (SSH File Transfer Protocol or Secure File Transfer Protocol) client is used for uploading grids and results. Creating a directory to organize your submission with the corresponding partipant's organization and/or last name is encouraged.
