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

See METIS 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 command for options to output the adjacency graph to a file.

create_graph / metis / [node | dual] / [nxadj] / [nadjncy]

create_graph/ lagrit / dual / jtetoff / jtet

LIMITATIONS

The metis option will not work on a hybrid mesh. Supported element types are tri, tet, quad, hex.METIS Interface to LaGriTThe /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 command.

See instructions in documentation of the metis command.
