| Abstract: |
| The quality of a boundary layer mesh is the key technique to ensure the accuracy of viscous calculations in computational fluid dynamics.This paper proposes a globally consistent high-quality boundary layer mesh construction algorithm for complex shapes.This method is based on the feature-oriented surface mesh domain decomposition technique,using the boundary lines and normal vectors of the surface mesh to construct the final contour frame line of the boundary layer.The contour frame line is used to generate a complete boundary layer mesh through the radial basis function and cubic spline interpolation algorithm.Through the analysis of typical examples,it can be seen that the accuracy and global consistency of the unstructured surface layer mesh generated by this method is high,and it is able to effectively avoid the local and global overlapping phenomenon of the complex shape boundary layer mesh. |
