secmesh process error

[whispers1104]

Hi Yexiang，
I installed the latest version of opstool and found some issues that may be bugs during use:

1. When importing opstool in a linux server, the content in cytriangle may not be found, which does not seem to happen in windows system. I tried to modify sectionproperties.pre, changing import cytriangle to import triangle seems to work, but I don't know if this will cause some problems.
2. The beam_sec parameter in ModelData.get_model_data: I set the section in section_library for each element as instructed in the document, but it seems to have a problem. In the windows system, only an empty folder (results_dir) appears, but there is no terminal output, while on the linux server, Segmentation fault (core dumped) will be displayed. I tried to find where the problem occurred. It should be in the get_beam_sec_info function in opstool\vis_get_model_base.py.
   The problem occurred in the line B = tr.triangulate(A, "qpa1000000000"), but unfortunately it stopped without any error message.

Hi Yexiang， 嗨Yexiang, I installed the latest version of opstool and found some issues that may be bugs during use:我安装了最新版本的 opstool，并在使用过程中发现了一些可能的 bug：

1. When importing opstool in a linux server, the content in cytriangle may not be found, which does not seem to happen in windows system. I tried to modify sectionproperties.pre, changing import cytriangle to import triangle seems to work, but I don't know if this will cause some problems.在Linux服务器上导入opstool时，可能会找不到cytriangle的内容，而在Windows系统中则不会出现这种情况。我尝试修改了sectionproperties.pre文件，将import cytriangle更改为import triangle，似乎可以解决问题，但我不知道这样做是否会引发其他问题。
2. The beam_sec parameter in ModelData.get_model_data: I set the section in section_library for each element as instructed in the document, but it seems to have a problem. In the windows system, only an empty folder (results_dir) appears, but there is no terminal output, while on the linux server, Segmentation fault (core dumped) will be displayed. I tried to find where the problem occurred. It should be in the get_beam_sec_info function in opstool\vis_get_model_base.py.ModelData.get_model_data中的beam_sec参数：我按照文档中的说明为每个元素设置了section_library中的截面信息，但似乎出现了问题。在Windows系统中，只出现了一个空文件夹（results_dir），但没有终端输出，而在Linux服务器上，则会显示“Segmentation fault (core dumped)”。我试图找出问题所在。问题应该出现在opstool\vis_get_model_base.py中的get_beam_sec_info函数中。
   The problem occurred in the line B = tr.triangulate(A, "qpa1000000000"), but unfortunately it stopped without any error message.问题出现在代码行中，但不幸的是，它没有给出任何错误提示就停止了。

Hi, it's been a long time since I replied😁. This seems to be a problem with the triangle library. The cross-section division is tied together and depends on another library, sectionproperties. In the latest version of opstool, the beam cross-section rendering function has been temporarily cancelled. In the future, we can consider a better rendering method.
