- download the zip file.
- download gmsh.exe (download gmsh) that satifies your operation system,and put gmsh.exe to your unzip file in step 1.
Note: If you encount AttributeError: module 'pygmsh' has no attribute 'opencascade', please uninstall current pygmsh module and install pygmsh with version 6.1.1
Generate sectional fibers based on python programming
The followings are some basic examples, and you can also find them in the download files.
