Generate sectional fibers based on python programming
Install the package in PyPI
pip install sectionFiberDivide
After installation through python script, then download gmsh (download gmsh) that satifies your operation system. And copy gmsh.exe to your working directory.
The followings are some basic examples, you can also obtain these examples using help(circleSection) and help(polygonSection).
