What is TetGen?
TetGen is an open source software for generating tetrahedral meshes of any 3D polyhedral domains. It generates exact Delaunay tetrahedralizations, boundary recovery, and conforming Delaunay tetrahedral meshes. The key features of TetGen include:
- Guaranteed quality tetrahedral meshes with good dihedral angles
- Handles complex geometries with holes, multiple regions, and nested domains
- Variety of options to generate conforming Delaunay meshes
- Fast and robust implementations for large scale meshing problems
- Ports to multiple platforms like Windows, Linux, and macOS
TetGen has applications in numerical simulations based on finite element or finite volume methods. The quality tetrahedral meshes allows accurate solutions for problems in structural mechanics, computational fluid dynamics, electromagnetics etc. It has bindings for programming languages like C++, Python, MATLAB, Julia etc. Overall, TetGen is a versatile, efficient and reliable open source software for generating tetrahedral meshes for complex 3D geometries.
