Quadrilateral Surface Mesh Generation Algorithm for CFD Model Based on Area-Preserving Parameterization

Abstract

Quadrilateral surface mesh generation is a difficult problem which has a great influence on the accuracy of numerical simulation in domain of computational fluid dynamics (CFD). It is time-consuming, and the engineers need rich experience in traditional mesh generation methods. In order to improve the degree of automation of the algorithm and speed up the iterative cycle of CFD model development, we present a new quadrilateral mesh generation method based on the area-preserving parameterization. The planar quadrilateral mesh can be generated by template and keep the geometric features because our area-preserving parameterization is bijective which can ensure that the characteristic lines which is marked on 3D model are not lost. Experimental results show that our algorithm can get high quality results and almost automatic.
