Support for new Mesh operations (fusion) #42

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
It would be nice to add these functionalities
 1- sequential assembly even though the mesh is parallel (ie do only the local matrix assembly and no communication to create the full matrix
2- Fusion of two conforming  meshes  (or disjoing)
3- Fusion of a mesh with a pair of iterators on a list of elements
4- Fusion of a mesh with elements  that share a face with an element of this 
mesh
5- Fusion of a mesh with elements  that share an edge with an element of this 
mesh
6- Fusion of a mesh with elements  that share a vertex with an element of this 
mesh
7- same things as fusion but the removal this time

the function merge() (feel/feeldiscr/meshimpl.hpp) has been added
see doc/manual/tutorial/stokes_pressure.cpp for an example

auto m1 = createGMSHMesh(...);
auto m2 = createGMSHMesh(...);
auto m = merge(m1,m2);

the meshes to be merged must be of the same type
