A new closed advancing-layer method for generating high-aspectratio
elements in the boundary-layer (BL) region is presented. This approach
utilizes a recent changing topology moving mesh strategy for deforming the
volume mesh as the BL is inflated. It handles very efficiently BL front collision
and produces a natural smooth anisotropic blending between colliding layers.
Moreover, it provides a robust strategy to couple unstructured anisotropic
mesh adaptation and high-aspect-ratio elements pseudo-structuredBLmeshes.
The proposed method is directly compared to a well established open
advancing-layer method. Results for typical aerospace configurations are presented
that provide a clear comparison between both methods as well as the effectiveness
of the changing topology moving mesh strategy.They show that the
closed method yields similar results in terms ofmesh quality and efficiency, and
that the considered moving mesh strategy is an efficient and effective method
for deforming the unstructured volume mesh.
