7 This mesh quality control highlights volumes sharing only one border with other volumes.
8 In other words, the volumes having all their nodes on the external border of the mesh are highlighted.
11 The highlighted volumes 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.

17 In this picture the over-constrained volume is displayed in red.
