[Dune] boundary projection (Marco Cisternino)

[Marco Cisternino]

Hi,
I'm debugging my code trying to insert Boundary Projection in parallel.
I'm doing it on a 3D ALUCubeGrid with 729 elements (9x9x9 elements)
Two issues:

Using just one proc:
during the insertion of boundary projection everything seems good; I 
insert boundary projections for each element boundary face on just one 
of the six sides of the grid, which means 81 faces; the factory shows me 
(using a debugger and looking at the bndVec_ attribute of the grid) that 
81 boundary faces are set to be projected; but when I create the grid 
only a group of these faces (42) are really set for projection. Why??

Using two procs:
I declare the factory for every procs in the communicator and I insert 
vertices, elements and boundaries using zero; everything works exactly 
in the same way till the grid creation, with the same result, i.e. the 
grid created on proc zero has the same projection problem I have with 1 
proc; then I call the loadBalance method but on proc 1 the bndVec_ and 
vertexProjection_ attributes, which are anyway incorrectly (42 in place 
of 81!) set for proc zero, point to 0!!!

Am I doing something wrong?? I used for BoundaryProjection the same 
logic I use for Vertices and Elements.
Any help will be really appreciated.

Thanks a lot.

Marco
