Abstract
Ten groups participating in the Cranked Arrow Wing Aerodynamics Project International (CAWAPI) within the NATO-RTO task group AVT113 have contributed viscous simulations of a full scale model of the F-16XL aircraft at different flight conditions. Three different classes of grids have been used by the different participants: a common structured grid, a common unstructured grid, and so-called individually tailored grids, which have been used by four participants: Lockheed Martin Aeronautics Company, University of Tennessee, Boeing Phantom Works, and EADS Military Air Systems. This paper focuses on the use of these individually generated grids. The different grid generation techniques and strategies (nonadapted, manually adapted, and solution-based adapted) are discussed and the solutions obtained in these individually tuned grids are compared with flight test data for different test cases.
