[Trilinos-Users] tree/co-tree identification

[Davood Ansari]

Hi every one

I am not sure if this makes sound to any one down here.
In FEM analysis, it happens very often that we need to split the graph
(the FE mesh is a graph) into two parts: the tree and the co-tree.

(the tree is any connected set of graph edges that meet all nodes and do not
make any closed loops).

I wonder if there are any ready made functions for the identification of the
tree and/or
the co-tree. If not, still may some of you be aware of any other substitute
for that purpose ?

Yours
Davood
