Abstract
This paper describes a new technology of mesh size control using a background overlay grid size function. A background overlay grid is generated first according to the defined size functions and then is used as the base grid for determining the mesh size at each point during the meshing process. The definitions, classifications, implementations and control algorithms of three types of size functions including a fixed size function, a curvature size function and a proximity size function are presented in detail. Meshing results with controlled mesh sizes are given, and considerations for further improvement are listed.
