A Modified Paving Technique for Quadrilateral Mesh Generation in Planar Regions

A modified paving technique for automatically generating quadrilateral meshes in planar regions is presented.First,the principle of the modified paving technique is discussed. Then,an optimization technique for quadrilateral meshes is proposed.The new paving technique eliminates a lot of shortcomings of the old technique and adds some new rules.It can generate high quality meshes in arbitrary planar regions and the obtained elements are uniform and regular.
