* **Applied algorithms** folder containing the references to the algorithms chosen at the construction of the mesh.
* **SubMeshes on Face** folder containing the sub-meshes defined on geometrical faces. There also can be folders for sub-meshes on vertices, edges, wires, shells, solids and compounds.
* **Groups of Faces** folder containing the groups of mesh faces. There also can be folders for groups of nodes, edges, volumes 0D elements and balls.

There is an alternative way to assign Algorithms and Hypotheses by clicking **Assign a set of hypotheses** button and selecting among pre-defined sets of algorithms and hypotheses. In addition to the built-in sets of hypotheses, it is possible to create custom sets by editing CustomMeshers.xml file located in the home directory. CustomMeshers.xml file must describe sets of hypotheses in the same way as ${SMESH_ROOT_DIR}/share/salome/resources/smesh/StdMeshers.xml file does (sets of hypotheses are enclosed between \<hypotheses-set-group\> tags). For example:

Changing sub-mesh priority
##########################
-If the mesh contains concurrent :ref:`sub-meshes <constructing_submeshes_page>`, it is possible to change the priority of their computation, i.e. to change the priority of applying algorithms to the shared sub-shapes of the Mesh shape.
+If the mesh contains concurrent :ref:`sub-meshes <constructing_submeshes_page>`, it is possible to change their :ref:`default priority <submesh_priority>`. Changing priority works in two ways:
+
+* For sub-meshes with assigned algorithms of same dimension generating mesh of *several dimensions*, it sets the order in which the sub-meshes are computed.
+* For the rest sub-meshes, it sets the order in which the sub-meshes are checked when looking for meshing parameters to apply to a sub-shape. Examples below present this way. To impose the order in which sub-meshes with uni-dimensional algorithms are computed, invoke **Compute Sub-mesh** command on sub-meshes in a desired order.
