| Abstract: | An efficient algorithm and programing scheme are presented for the automatic mesh generation ofarbitrary planar domains into triangular elements, which are based on the facts,1.arbitrary multiplyconnected regions can always be divided into triangular elements.2.active nodes in this region tend tozero with the generation of triangular elements.Methods for improving the quality of elements aregiven in this paper. The structure of this program has a well-knit plot with little input data, higherquality and stability. |

| Keywords: | multiply connected region active node triangular element mesh generation mesh optimization |
