+Max Element Volume hypothesis
+#############################
+
+**Max Element Volume** hypothesis is applied for meshing of 3D objects composing your geometrical object. Definition of this hypothesis consists of setting the **maximum volume** of 3D meshing elements (depending on the chosen meshing algorithm it can be **hexahedrons** or **tetrahedrons**), which will compose the mesh of these 3D objects.

+
+Renumber hypothesis
+###################
+
+**Renumber** hypothesis is applied for meshing of 3D objects along with **Hexahedron (i,j,k)** algorithm.
+
+Order and hence numbering of hexahedral elements in the structured mesh generated by **Hexahedron (ijk)** algorithm depends on the order of faces in a block geometry. Nodes are not in a structured order, since geometrical edges and faces are discretized before construction of hexahedra. **Renumber** hypothesis allows for getting hexahedra and nodes ordered like in a structured grid.
+
+.. image:: ../images/block_renumber_hyp.png
+ :align: center
+
+**Renumber** hypothesis allows to define direction of **i, j** and **k** axes of a block. For that you specify two vertices of the block
+
+* **Vertex (0,0,0)** located at the origin of the block local coordinate system.
+* **Vertex (0,0,1)** located at the end of **k** axis of the block.
+
+Axes **i** and **j** are found automatically using the right-hand rule.
+
+For blocks with edges parallel to the axes of global coordinate system, their local coordinate system by default is defined as having axes parallel to the global ones. So, for such blocks specification of vertices is optional, it is enough just to assign **Renumber** hypothesis.
+
+**See Also** a sample TUI Script of a :ref:`tui_block_renumber` operation.

* You can specify the **Coordinates** of grid nodes. **Insert** button inserts a node at **Step** distance (negative or positive) from the selected node. **Delete** button removes the selected node. Double click on a coordinate in the list enables its edition. **Note** that node coordinates are measured along directions of axes that can differ from the directions of the Global Coordinate System.
* You can define the **Spacing** of a grid as an algebraic formula *f(t)* where *t* is a position along a grid axis normalized at [0.0,1.0]. *f(t)* must be non-negative at 0. <= *t* <= 1. The whole extent of geometry can be divided into ranges with their own spacing formulas to apply; a t varies between 0.0 and 1.0 within each **Range**. **Insert** button divides a selected range into two. **Delete** button adds the selected sub-range to the previous one. Double click on a range in the list enables edition of its right boundary. Double click on a function in the list enables its edition.
+
+.. note:: The actual grid spacing can slightly differ from the defined one. This is done for the best fitting of polyhedrons and for a better mesh quality on the interval boundaries. For example, if a constant **Spacing** is defined along an axis, the actual grid will fill the shape's dimension L along this axis with round number of equal cells: Spacing_actual = L / round( L / Spacing_defined ).
* **Fixed Point** group allows defining an exact location of a grid node in the direction defined by spacing. The following cases are possible:
