\n <b>Mesh quality control</b> in MESH is destined for visual control of the generated mesh.
help of a scalar bar, which is displayed near the presentation of your
mesh.
-There are 1D, 2D and 3D quality controls.
+There are four types of quality controls, corresponding to node, edge,
+face and volume entity type.
