Abstract
A hybrid method for the automatic generation of finite element meshes is presented. The original domain awaiting to be meshed is divided into two areas, the squares of the interior part are split into isosceles right triangles, which results in uniform meshes with excellent internal triangles like the Almost Regular Triangulations. The region near boundary is meshed by advancing front technique (AFT). Compared with other methods, it’s capable of automatically and adaptively generating meshes with reasonable quality. It is also easy to implement in program, and save the CPU time greatly. The method is proved to be effective by application to calculate the RCS of sphere and cylinder.
