Dear Algiane
I am using mmg2d for meshing a domain of square with another square inside it. All the boundary refs are appended using (MMG2D_Set_edge(mmgMesh, edges[2i], edges[2i+1], edgeMark[i], i+1) ; The ref of the outer square is 1 and that of the inner sqare is 1. However after the refining, the refers of the edges are not preserved? I searched the forum, and found that this problem has been solved. However, what is the possible problems with my setting?
the output mesh is below

In the section of Edge, there are edges with Refs with 0.
.
) the problem?
