Enhanced Advancing Front Technique with Extension Cases for Initial Triangular Mesh Generation
During the element creation procedure of initial mesh generation using the Standard Advancing Front Technique (SAFT), there is a possibility where a conflict of undecided element occurs which do not follow the normal cases. The authors proposed a direct approach to tackle this kind of problem by extending the two normal cases in SAFT to the total number of five cases of consideration during the element creation procedure in initial mesh generation. The approach is called as Enhanced Advancing Front Technique-1 (EAFT-1). The aim of this paper is to improve the SAFT in order to tackle directly such problem of sudden invalid triangular element without having to re-order back the Front list and without erasing the existing element in the initial mesh generation.
