\n In MESH you can perform some Boolean operations on groups, which
belong to one and the same mesh.

\anchor union_anchor
-<h2>Union of two groups</h2>
+<h2>Union of groups</h2>
This operation allows to create a new group in such a way that all
mesh elements that are present in the initial groups will be added to
the new one.
