Application of strand meshes to complex aerodynamic flow fields

The strand-adaptive Cartesian approach is an innovative mesh generation approach for external aerodynamics that presents signi cant advantages over established methods in terms of grid automation, accuracy, and scalability. In this work, the approach is evaluated for complex geometries and ow elds. Speci cally, strand length and strand vector smoothing are studied at a fundamental level in order to understand their e ects on computed solutions. Recommendations are given for these parameters to improve solution quality. Using these recommendations, results of three applications using the strand-adaptive Cartesian approach are given, including a NACA wing, isolated V-22 (TRAM) rotor in hover, and the DLR-F6 wing-body transport. The results from these cases show that the strand approach can successfully resolve near-body and o -body features as well as or better than established methods.
