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，为实现三维有限元模拟的可视化提供了一条简便而高效的途径
A 3D visualization method based on AutoCAD is introduced. In the AutoCAD platform, the development of interface procedures, the formation of graphics exchange files (DXF), accurately and efficiently to achieve three-dimensional solid mesh and three-dimensional surface mesh visualization. The method only needs to hide the graphics generated by the DXF file with the HIDE command in AutoCAD, eliminating the need to compile complex blanking programs. In addition, this method can also be used to realize the velocity field of 3D FEM simulation and the visualization of contour maps of field variables such as stress and strain. This method tightly links the finite element numerical simulation with AutoCAD and provides a simple and effective way to visualize the three-dimensional finite element simulation
