Automatic adaptive finite element mesh generation over arbitrary two-dimensional domain using advancing front technique

The basic principles for the generation of adaptive finite element meshes o ver arbitrary two-dimensional domains using the advancing front technique a re described. Methods to generate triangular and quadrilateral meshes are a lso presented. In addition to the description of the mesh generation algori thms, implementation details concerning both the speed and memory requireme nt are given. Mesh generation examples demonstrate that the proposed mesh g enerator is capable of discretizing the problem domain into a well-graded, high quality adaptive finite element mesh with element sizes compatible wit h the user specification. The whole automatic mesh generation program can b e run on an IBM PC compatible machine and meshes with up to 9000 elements c an be generated within a practical time limit.
