摘要
研究有限元计算中的网格重划分技术,基于ANSYS和二次开发语言,提出了基于APDL和UPFs和基于APDL和Rezone技术两种网格重划分方法,此外,基于提出的第二种网格重划分方法,对冲孔剪切带进行了模拟,得到了剪切带的等效应力分布,可知,通过网格重划分技术的应用有效的提高了收敛性和计算精度。
The remeshing in FEM was studied. Based on ANSYS,APDL and UPFs two kind simulation methods were proposed,one was based on APDL and UPFs,the other was based on APDL and Rezone. Moreover,based on the second simulation method proposed,punching process was simulated. The equivalent stress distribution in the shear zone was obtained. Through analyzing,the remeshing effectively improves the convergence and computing precise.
