.geom是什么文件的扩展名

在做火灾条件下的钢结构热应力分析，现在卡在如何将温度边界条件（随时间和空间变化）导到ANSYS这一步。有一个网上的开源程序可以做，但前提是需要从ANSYS导出两个文件 “nodes.dat” ， “elements.dat”，然后说需要用到Macros，有提供macros文件“ansys2ftmi.geom”， “ansys2ftmi_shell.geom”。我对ANSYS不太了解，但看帮助，好像.geom不是macros的扩展名，有人知道这个扩展名吗？ 下面是程序user guide关于如何从ANSYS导出 “nodes.dat” ， “elements.dat”文件的原文： The interface with ANSYS is developed using surface effect elements, so the information presented in the files “nodes.dat” and “elements.dat” are related to those surface effect elements. To help in the generation of the surface effect elements and these two input files, some ANSYS macros were created. It is possible to export the mesh information using the macros “ansys2ftmi.geom” or “ansys2ftmi_shell.geom”. The first can be used for solid elements and the second one is devoted to shell elements. The shell element file creates interfaces on both sides (top and bottom layers) of the shell elements 1. These macros were designed to create interface elements attached to the boundary element faces between solid and gas. To select just the exposed surfaces related to a specific scenario, those surfaces can be selected in ANSYS before running the macros (Select Entities > Areas). The macros are available at Utilities/Structural_ Interaction/fds2ftmi/scrips. |
