+
+\n Use Existing Elements algorithms allow to define the mesh of a geometrical
+object by the importing suitably located mesh elements from another
+mesh. The mesh elements to import from the other mesh are to be contained in
+groups. If several groups are used to mesh one geometry, validity of
+nodal connectivity of result mesh must be assured by connectivity of
+the source mesh; no geometrical checks are performed to merge
+different nodes at same locations.
+<br> The source elements must totally cover the meshed geometry.
+The source elements lying partially over the geometry will not be used.
+<br>
+These algorithms can be used to mesh a very complex geometry part by
+part, by storing meshes of parts in files and then fusing them
+together using these algorithms.
