A. Appendix 1 : Files format (MESH and SOL)

Mmg3d reads and writes mesh files with MESH format and solutions (metric or displacement) with SOL format.

These files formats allows to read/write binary and ASCII files. They are composed by one file (xx.mesh or xx.meshb or xx.sol or xx.solb) which contains all needed information for mesh (or solution) description.

On the following paragrah, we will describe first the ASCII format then the binary one.
