ISpliter: an intelligent and automatic surface mesh generator using neural networks and splitting lines

Advances in Aerodynamics

Table 2 The quality of the meshes generated by the baselines and ISpliter. They are the average skewness, the minimum skewness, the average minimum angle, and the minimum minimum angle of all elements, respectively. The best values are bolded
