-\n This mesh quality control highlights faces sharing only one of its borders with other faces.
+\n This mesh quality control highlights faces sharing only one of its borders with other faces. In other words the faces having all there nodes on the external border of the mesh are highlighted.
+
+\note The highlighted faces are actually over constrained only if, at the computation time,
+the boundary conditions on the borders where the nodes are located are all Dirichlet boundary conditions.
