- Abstract
- In the process of finite element analysis, mesh generation is tedious job which consumes tremendous times.
Therefore, the automation of well shaped mesh generation from the minimal boundary input data is desirable to improve reliability and accuracy of the analysis and also to reduce the process time of the entire design process.
The automation of triangular mesh generation has been relatively well treated due to its robustness and ease of handling when compared to rectangular element mesh generation.
In this study, the offset method developed previously for generating plane rectangular element mesh has been corrected and modified to generate triangular element mesh on the B-spline surface having arbitrary holes.
The result shows that the generated triangular mesh has the average aspect ratio over 0.9.
The designed arbitrary surface shape has been interactively constructed by non-uniform B-spline theory for triangular mesh generation.
