+In MESH you can create a group of elements of a certain type. The main way to create a group, is to
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. See more about filters on the :ref:`selection_filter_library_page` "Selection filter library" page.

To create a group on geometry check **Group on geometry** in the **Group** **type** field. The group on geometry contains the elements of a certain type generated on the selected geometrical object. Group contents are dynamically updated if the mesh is modified. The group on geometry can be created only if the mesh is based on geometry.
-To define a group, click the *Selection* button and choose
