This type has a limitation on the number of segments: one pair of opposite sides must have the same number of segments, the other pair must have an even total number of segments. In addition, the number of rows between sides with different discretization should be enough for the transition. Following the fastest transition pattern, three segments become one (see the image below), hence the least number of face rows needed to reduce from Nmax segments to Nmin segments is log<sub>3</sub>( Nmax / Nmin ).

About quality controls
**********************
-.. note::
- **Mesh quality control** in MESH is destined for visual control of the generated mesh.
+**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.
* **Edge Controls** provides access to the edge quality controls;

To create any **Quadratic Element** specify the nodes which will form your element by selecting them in the 3D viewer with pressed Shift button and click *Selection* button to the right of **Corner Nodes** label. 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. Then you will be able to click **Apply** or **Apply and Close** button to add the element to the mesh.

The MESH module contains a set of meshing algorithms, which are used for meshing entities (1D, 2D, 3D sub-shapes) composing geometrical objects.
+.. note:: Algorithms added to the module as plug-ins are described in documentation of the plug-ins.

An algorithm represents either an implementation of a certain meshing technique or an interface to the whole meshing program generating elements of several dimensions.

Compound Mesh is a combination of several meshes. All elements and groups present in input meshes are present in the compound mesh. However, it does not use geometry or hypotheses of the initial meshes.

- * In Geometry module, by creation of a group (**New Entity > Group > Create Group** menu).
- * In Mesh module, by :ref:`subshape_by_mesh_elem` generated on a sub-shape of interest. This way is accessible if the mesh is already computed.

select in the **Mesh** menu **Create Group** item (also available in the context menu of the mesh).
To create a group you should define the following:
the following ways:
* By adding all entities of the chosen type existing in the mesh. For this, turn on the **Select All** check-box. In this mode all controls, which allow selecting the entities, are disabled.
-* By choosing entities manually with the mouse in the 3D Viewer. For this, turn on the **Enable manual edition** check box. You can click on an element in the 3D viewer and it will be highlighted. After that click the **Add** button and the ID of this element will be added to the list. The **Set filter** button allows to define the filter for selection of the elements for your group.

* If **Create joint elements** option is activated, flat elements are created on the duplicated nodes: a triangular facet shared by two volumes of two groups generates a flat prism, a quadrangular facet generates a flat hexahedron.

These groups are named according to the position of the group in the list of groups: group "j_n_p" is a group of flat elements that are built between the group \#n and the group \#p in the group list.

#. There are two optional parameters, which can be very useful:
-#. If the path of extrusion is curvilinear, at each iteration the extruded elements are rotated to keep its initial angularity to the curve. By default, the **Base Point** around which the elements are rotated is the mass center of the elements (note that it can differ from the gravity center computed by *Geometry* module for the underlying shape), however, you can specify any point as the **Base Point** and the elements will be rotated with respect to this point. Note that only the displacement of the **Base Point** exactly equals to the path, and all other extruded elements simply keep their position relatively to the **Base Point** at each iteration.

-#. The elements can also be rotated around the path to get the resulting mesh in a helical fashion. You can set the values of angles at the right, add them to the list of angles at the left by pressing the **"Add"** button and remove them from the list by pressing the **"Remove"** button.

There are three types of groups different by their internal organization:
#. **Standalone group** is a static set of mesh entities. Its contents can be explicitly controlled by the user. Upon removal of the entities included into the group, e.g. due to modification of meshing parameter, the group becomes empty and its content can be restored only manually. Hence it is reasonable to create standalone groups when the mesh generation is finished and mesh quality is verified.
- .. warning:: Creation and edition of large standalone groups in :ref:`creating_groups_page` dialog using manual edition is problematic due to poor performance of the dialog.
+ .. warning:: Creation and edition of large standalone groups in :ref:`Create group <creating_groups_page>` dialog using manual edition is problematic due to poor performance of the dialog.
#. **Group on geometry** is associated to a sub-shape or a group of sub-shapes of the main shape and includes mesh entities generated on these geometrical entities. The association to a geometry is established at group construction and cannot be changed. The group contents are always updated automatically, hence the group can be created even before mesh elements generation.
-#. **Group on filter** encapsulates a :ref:`filters_page`, which is used to select mesh entities composing the group from the whole mesh. Criteria of the filter can be changed at any time. The group contents are always updated automatically, hence the group can be created even before mesh elements generation.
