But it is a time consuming, complex, and even very difficult work to generate meshes by handwork 然而手工構(gòu)造一個(gè)有效的網(wǎng)格剖分是一項(xiàng)費(fèi)時(shí)、繁瑣、甚至極其困難的工作。
An original mesh generation method based on the nc track points of tool surfaces is proposed here, the method can automatically generate meshes consisting of only quadrilateral elements, which is desirable for better accuracy and efficiency of simulation . besides, an automatic local coarsening algorithm for structured quadrilateral meshes is also developed . for arbitrary discrete points on auto body surfaces, an automatic triangulation method is adopted and a series of mesh optimization methods with given constraint conditions are proposed 創(chuàng)新地提出了基于模具型腔表面nc數(shù)控軌跡點(diǎn)的全自動(dòng)四邊形網(wǎng)格生成算法,提出了結(jié)構(gòu)化四邊形網(wǎng)格局部自動(dòng)優(yōu)化算法,研究了基于車身曲面離散點(diǎn)的三角形網(wǎng)格自動(dòng)生成算法,并提出了給定約束條件的三角形優(yōu)化算法,探討性地研究了基于模具曲率半徑的板料初始網(wǎng)格局部自動(dòng)細(xì)化算法。
