| Abstract: | A fully automatic initial mesh generating algorithm based on the Delaunay triangulation technique is presented. A simple but effective method for imposing the boundary constraint is given. Examples are provided to show the performance of the algorithm. As an important part of a geometrybased, fast, effective, automatic and adaptive mesh generating scheme proposed by the authors, the initial mesh generating algorithm requires only the characteristic venices of the objective boundary and the boundary line segments as the original input data. The algorithm is suitable for any complex planar domain. |
