Please pardon the lack of experience, but I have a closed triangulation
such as this:

                $MeshFormat
                2 0 8
                $EndMeshFormat
                $Nodes
                5
                1   0.0   0.0   0.0  
                2   1.0   0.0   0.0  
                3   0.5   1.0   0.0  
                4   0.5   0.6  0.75  
                5   0.5   0.1  0.75  
                $EndNodes
                $Elements
                6
                1 2 2 1 0   2 3 1                
                2 2 2 1 0   5 4 2                
                3 2 2 1 0   4 3 2                
                4 2 2 1 0   4 1 3                
                5 2 2 1 0   1 4 5                
                6 2 2 1 0   5 2 1                
                $EndElements

and simply wish to generate a conformal linear tetrahedral mesh.
However, when I attempt a 3D mesh, nothing happens. Do I need to
manually define some sort of volume to which these triangles belong?
Puzzled,

Albert Hines
