讨论了对能够处理一般几何形状和网格渐变的全自动有限元网格生成器的需求。提出了一种全自动二维和三维网格生成的具体方法，以满足有界型网格细化的需求。这些程序，基于层次空间分解，允许有效的先验和后验网格细化。还概述了一种能够产生粗网格的方法，该方法具有无界指数网格渐变，可以用于可选的预处理。
The need for fully automatic finite element mesh generators capable of dealing with general geometries and mesh gradations is discussed. A specific approach to fully automatic two- and three-dimensional mesh generation that meets these needs for meshes with boundedh-type of mesh refinements is presented. These procedures, based on hierarchic spatial decompositions, allow for efficient a priori and a posteriori mesh refinements. An approach capable of producing coarse meshes with the unbounded exponential mesh gradations as desired for optionalh-prefinements is also outlined.
