Fiber Section Mesh

The module opstool.preprocessing provides a series of classes and functions for fiber section mesh generation, based on shapely and sectionproperties. The pacakge sectionproperties utilizes finite element methods to calculate the geometric properties of sections, including single-material section and composite section.

Module preprocessing provides two main classes SecMesh and Rebars, and some functions, including offset(), add_circle(), add_polygon() and add_material(), to help create fiber cross-section.
