摘要
介绍一种基于ＡｕｔｏＣＡＤ的三维有限元模拟可视化方法。在ＡｕｔｏＣＡＤ平台上， 开发接口程序， 生成图形交换文件（ＤＸＦ），能够准确而高效地实现三维实体网格和三维曲面网格的可视化。该方法只需对ＤＸＦ文件生成的图形， 用ＡｕｔｏＣＡＤ中ＨＩＤＥ命令进行消隐， 不再需要编制复杂的消隐程序。此外，还可用该方法实现三维有限元模拟的速度场以及应力和应变等场变量等值线图的可视化。该方法把有限元数值模拟与ＡｕｔｏＣＡＤ紧密衔接起来。
A visualization method of 3D finite element simulation is presented by developing a simple interface program for drawing exchange files (DXFs)based on the platform of AutoCAD software.Visualization of 3D solid grid and 3D curved grid can be obtained accurately and efficiently without complex program of removing hidden lines.Moreover, visualization of velocity field can be carried out, distributions of stress field and strain field etc.can be expressed with isogram.It is a convenient aod practical method for data exchange between finite element simulation software and AutoCAD software.
