Title: The automatic generation of quadrilateral mesh-I:the method of domain division
Abstract: A method combined density control and domain division for automatic quadrilateral mesh generation is presented,which is especially suitable for the bulk forming analysis.The key techniques algorithms in the method are presented,such as the geometry representation,the determination of the critical points,the generation of the mesh density,node generation,boundary element generation,splitting criteria,pattern matching,shape improvement and bandwidth minimization etc.Based on the method,the software AUTOMESH for quadrilateral mesh generation is developed successfully.Some examples of mesh generation are given to demonstrate the reliability of the method.
