Serialize the mesh data structure and provide save()/load() interface

GoogleCodeExporter commented 9 years ago 
The current implementation being debugged now allows to do something like this

{{{

    tic();
    auto is_mesh_loaded = mesh->load( _name="mymesh",_path=".",_type="text" );
    toc( "load" );

    if ( !is_mesh_loaded )
    {
        tic();
        Log() << "Generating mesh using gmsh...\n";
        mesh = createGMSHMesh( _mesh=new mesh_type,
                               _update=MESH_CHECK|MESH_UPDATE_FACES|MESH_UPDATE_EDGES|MESH_RENUMBER,
                               _desc=domain( _name=( boost::format( "%1%-%2%" ) % shape % Dim ).str() ,
                                             _shape=shape,
                                             _dim=Dim,
                                             _h=X[0] ),
                               _partitions=this->comm().size() );
        Log() << "Saving mesh...\n";
        mesh->save( _name="mymesh",_path=".",_type="text" );
        toc("generate+save");
    }
    else
    {
        tic();
        mesh->save( _name="mymesh2",_path=".",_type="text" );
        toc("save");
    }

}}}

The implementation of this feature is available in the branch serialmesh on 
Feel++ google code (git)

The status  is that the save()/load() function are implemented and are working. 
The isssue is that send/recv using boost.mpi still does not work (I am 
investigating this...)

in case of two procs exchange the mesh: you can visualize them the two meshes
and see they have been swapped from the initial partitioning

added encode() and decode() in mesh data structure to compress it 
it is used to send/receive meshes

The change for this is done now.See doc/manual/tutorial/mymesh.cpp for some 
examples
