FREEFEM++_MSH, a data directory which contains examples of the mesh files created by the FreeFem++ program, which use the extension ".msh".
Note that the GMSH program creates mesh files that use the ".msh" extension, but which are an entirely different format.
The msh file format is obliquely described in section 12.5 of the FreeFem++ documentation.
At least for the 2D case of a triangular mesh, the format seems to be as follows:

BAMG, examples which illustrate the use of BAMG, a program for generating 2D meshes that can be used to define the geometry for the the finite element package FREEFEM++.
FREEFEM++, examples which illustrate the use of the FREEFEM++ package, a high-level integrated development environment for the numerical solution of nonlinear multiphysics partial differential equations (PDE's) in 2D and 3D.
FREEFEM++_MSH_IO, a FORTRAN90 library which can read and write files used by the FreeFem++ finite element program to store mesh information.
MITCHELL_FREEFEM++, examples which illustrate the implementation of the Mitchell 2D elliptic partial differential equation (PDE) test problems using FREEFEM++.
MESH_SAMPLE does not solve a problem; it simply generates a mesh on a circle, and saves the mesh to a file. This example is meant to illustrate the structure of the mesh file format that is used by FreeFem++.
