Simplicial

Simplicial provides a framework to work with simplicial meshes of arbitrary dimension.
The data structure is "layered" so that any sort of homogeneous mesh can be represented.
A specialized structure allows the representation of meshes with explicit adjacency
information between top simplexes.
Also, a further specialized structure allows the representation of so-called
"liquidus" hypersurfaces that describe the behaviour of multi-component materials.

Simplicial implements indexed data structures with all the fundamental
functionalities (i.e., file I/O, mesh construction/destruction, traversal).
It is written in C++ and includes support for reading and writing a custom file
format with extension .CPX.
