4.3.0.1 Details for the structure MMG_Mesh :

this structure can be decomposed on five parts :

1. the general mesh informations:
   number of nodes (np) and maximal number of nodes which will be generated (npmax)
   number of surface triangles (nt) and maximal number of triangles which could be generated (npmax)
   number of tetrahedra (ne) and maximal number of tetrahedra which could be generated (nemax)
   

2. the vertex (MMG_pPoint point):
   This part contains for all the vertex, their coordonnates and their logic (reference)
   
3. the surface triangles (MMG_pTria tria):
   This part contains for all the surface triangles, the points number of their three vertex and their logic (reference),
   
4. the tetrahedra (MMG_pTetra tetra):
   This part contains for all the tetrahedra, the points number of their four vertex and their logic (reference, number of subdomain),
   
5. the displacement prescribed on each vertex (in rigid movement case, see 5)(MMG_pDispl disp):
   This part contains a displacement vector for all vertex mesh.
