Study of a practical dividing method for the plane finite element grid

PU Jun-ping,YAO Yu-long(College of Civil Engineering & Architecture,Zhejiang University of Technology,Hangzhou 310032,China)  
The generation of grid is the precondition and foundation of plane finite element calculation,but poor units will be generated when there are irregular boundaries,which will affects the calculation results.Referring matured quadrilateral grid generation methods,a Visual basic program based on structured finite element grid portioning is developed,which will generate regular quadrilateral grid.It has the characteristics such as: easy to use,grid density and united quantity could be controlled,the data generated are brief and practicable,especially for finite element analysis of small structures.
