"Mesh computation/Show a computation result notification" preference
to the "Never" value. This option gives the possibility to control mesh
computation reporting. There are the following possibilities: always
mesh created using these algorithms should be exported into a python
script, edited and then imported into the GUi.
-Consider trying a sample script for construction of a mesh from our
-\ref tui_creating_meshes_page "TUI Scripts" section.
+<li>It is possible to calculate the eventual mesh size
+before \b Compute operation. For this, select the mesh in the <b>Object
+Browser</b> and from the \b Mesh menu select \b Evaluate. The result of
+evaluation will be displayed in the following information box:

+If the mesh contains concurrent submeshes, it is possible to change
+the priority of their computation, i.e. to change the priority of
+applying algorithms to the shared subshapes of the Mesh shape.</li>
+
+<em>To change submesh priority:</em>
+
+<li>Choose "Change submesh priority" from the Mesh menu or a popup menu. The opened dialogue
+shows a list of submeshes in the order of their priority.
+
+There is an example of submesh order modifications of the Mesh created on a Box
+shape. The main Mesh object:
+<ul>
+<li><i>3D</i> <b>Tetrahedron (Netgen)</b> with Hypothesis<b>Max Element Volume</b></li>
+<li><i>2D</i> <b>Triangle (Mefisto)</b> with Hypothesis<b>Max Element Area</b>
</li>
+<li><i>1D</i> <b>Wire discretisation</b> with <b>Number of Segments</b>=20</li>
+</ul>
+The first submesh object <b>Submesh_1</b> created on <b>Face_1</b>
+is:
+<ul>
+<li><i>2D</i> Netgen 1D-2D with Hypothesis <b>Netgen Simple parameters</b>
+(Number of Segments = 4)</li>
+</ul>
+The second submesh object <b>Submesh_2</b> created on <b>Face_2</b>
+is:
+<ul>
+<li><i>2D</i> Netgen 1D-2D with Hypothesis <b>Netgen Simple parameters</b>
+(Number of Segments = 8)</li>
+</ul>
+
+And the last submesh object <b>Submesh_3</b> created on <b>Face_3</b>
+is:
+<ul>
+<li><i>2D</i> Netgen 1D-2D with Hypothesis <b>Netgen Simple parameters</b>
+(Number of Segments = 12)</li>
+</ul>
+The submeshes become concurrent if they share subshapes that can be meshed
+with different algorithms (or different hypothesises).
+In the example, we have three submeshes with concurrent algorithms,
+because they have different hypotheses.
+
+The first mesh computation is made with:
+\image html mesh_order_123.png
+<center><em>"Mesh order SubMesh_1, SubMesh_2, SubMesh_3"</em></center>
+\image html mesh_order_123_res.png
+<center><em>"Result mesh with order SubMesh_1, SubMesh_2, SubMesh_3 "</em></center>
+
+The next mesh computation is made with:
+\image html mesh_order_213.png
+<center><em>"Mesh order SubMesh_2, SubMesh_1, SubMesh_3"</em></center>
+\image html mesh_order_213_res.png
+<center><em>"Result mesh with order SubMesh_2, SubMesh_1, SubMesh_3 "</em></center>
+
+And the last mesh computation is made with:
+\image html mesh_order_321.png
+<center><em>"Mesh order SubMesh_3, SubMesh_2, SubMesh_1"</em></center>
+\image html mesh_order_321_res.png
+<center><em>"Result mesh with order SubMesh_3, SubMesh_2, SubMesh_1 "</em></center>
+
+As we can see, each mesh computation has a different number of result
+elements and a different mesh discretisation on the shared edges (the edges
+that are shared between <b>Face_1</b>, <b>Face_2</b> and <b>Face_3</b>)
+
+Additionally, submesh priority (the order of applied algorithms) can
+be modified not only in a separate dialog box, but also in the
+<b>Preview</b>. This helps to preview different mesh results,
+modifying the order of submeshes.
+\image html mesh_order_preview.png
+<center><em>"Preview with submesh priority list box"</em></center>
+
+If there are no concurrent submeshes under the Mesh object, the user will see the
+following information.

+<center><em>"No concurrent submeshes detected"</em></center>
