Detailed Description

Base framework for the mesh generation classes.

This module contains the core framework used by the other mesh generation modules, and implements shared functionality including the tessellation of larger elements into tetrahedra, fibre field generation and mesh file output.

For information on the detail of the implementation of this module and other derived classes, see the meshing section of the carputils documentation.
