+CREATE_GRAPH
+
+> Create a node or dual (element) adjacency graph. If node option is selected,
+the graph of node adjacency is created, if dual option is selected, the graph
+of element adjacency (dual graph) is created.
+
+For details of METIS algorithms and descriptions of the third command line
+argument see:
+
+[http://glaros.dtc.umn.edu/gkhome/views/metis](http://glaros.dtc.umn.edu/gkhom
+e/views/metis)
+
+See [METIS ](metis.html)documentation for description of graph format.
+
+The default name of the attributes that are created are different depending on
+which option (metis or lagrit) is used.

+
+> See the [dump](DUMP2.html) command for options to output the adjacency graph
+to a file.`

+`
+
+  
+LIMITATIONS
+
+> The metis option will not work on a hybrid mesh. Supported element types are
+tri, tet, quad, hex.
+
+>
+
+> The /lagrit/ option will only produce the dual adjacency graph. The only
+option for the name of the graph arrays are jtetoff and jtet. The present
+implementation is just a wrapper on the [geniee](GENIEE.html) command.
