[petsc-users] non-manifold DMPLEX

[TARDIEU Nicolas]

Dear PETSc Team,

Following a previous discussion on the mailing list, I'd like to experiment with DMPLEX with a very simple non-manifold mesh as shown in the attached picture : a cube connected to a square by an edge and to an edge by a point.
I have read some of the papers that Matthew et al. have written, but I must admit that I do not see how to start...
I see how the define the different elements but I do not see how to specify the special relationship between the cube and the square and between the cube and the edge.
Once it will have been set correctly, what I am hoping is to be able to use all the nice features of the DMPLEX object.

Best regards,
Nicolas
