Automatic generation of structured multiblock boundary layer mesh for aircrafts

摘要

Structured meshes are widely utilized in the aircraft industry, despite their requirement for significant interaction between the engineers and the commercial software used in the generation process. In this research, we introduce part of our achievements while investigating the automatic generation techniques for structured meshes of arbitrary aircrafts. First, we present a data structure that eliminates the many-to-many relationship between various physical entities representing the discrete mesh. Second, we propose a novel method that can automatically generate a structured multiblock boundary layer mesh using an input surface mesh. Finally, we verify the proposed method with three cases (i.e., convex/concave steps, a four-rudder missile and the F6 wing-body half model) by the metrics Jacobian, included angles and aspect ratios. These experiments show that our proposed method can automatically generate structured multiblock boundary layer mesh for aircrafts.
