Automatic Quadrilateral Mesh Generation Algorithm for Curved Surface with Line Constraints
Qifu Wang · Mechanical Science and Technology · 2003
A quadrilateral mesh generation algorithm is presented for curved surface with line constraints. The algorithm consists of two steps: firstly, the triangular mesh of curved surface is generated by constraint Delaunay method; and then by the definition of several topological operators, the triangular mesh is transferred into quadrilateral mesh using the advancing-front techniques. Compared with previous methods , our method can deal with special geometry such as line constraints. Finally, an example is given to verify the method.
