Efficient Method for Cell Size Control and Deformation of Unstructured Quadrilateral Grid System

摘要

In this paper grid generation and cell size control of unstructured quadrilateral grids is described. The current approach uses conventional Advancing Front Method which is used to generate unstructured triangular grids. Grid cell size control is done by using closeness-based global interpolation method controlled by pre-described control elements. Algorithm and procedure for quadrilateral grid generation using AFM method and cell size control method are described. Application of current approach for quadrilateral grid generation is demonstrated, and the flexibility of cell size control of the proposed method is successfully confirmed.
