Microgen is a Python library designed to facilitate microstructure generation and meshing. Here are its core features:
- Repeated cells: Generation of lattice structures such as octet trusses and honeycombs.
- Triply Periodic Minimal Surfaces (TPMS): TPMS-based lattice generation known for favorable physical (mechanical, thermal, ...) properties like low density and large surface area.
- Virtual composites microstructures: Generation of basic reinforcement geometries, including spheres, cylinders, ellipsoids, and more.
- 3D Voronoi tessellation: Simulation of granular materials and polycrystalline metals.
- Meshing: Regular and periodic meshing using Gmsh, remeshing using Mmg.
Generation of 3D objects is achievable through functions that utilize Open CASCADE (via Cadquery) or VTK (using PyVista). Neper offers tools for 3D tessellation, while Gmsh handles the generation of both regular and periodic meshes, with Mmg handling remeshing tasks.
