 **********************
 
-.. note:: 
 **Mesh quality control** in MESH is destined for visual control of the generated mesh.
 
 Application of a definite quality control consists of usage of the corresponding algorithm, which calculates a value of a definite geometric characteristic (Area, Length of edges, etc) for all meshing elements, composing your mesh. Then all meshing elements are colored according the calculated values. The reference between the coloring of the meshing elements and these calculated values is shown with the help of a scalar bar, which is displayed near the presentation of your mesh.

Their numbers will appear in the dialog box as **Corner Nodes** (alternatively you can just input numbers in this field without selection; note that to use this way the mesh should be selected before invoking this operation). The edges formed by the corner nodes will appear in the table. To define the middle nodes for each edge, double-click on the respective field and input the number of the node (or pick the node in the viewer). For bi-quadratic and tri-quadratic elements, your also need to specify central nodes. As soon as all needed nodes are specified, a preview of a new quadratic element will be displayed in the 3D viewer.
