about mesh2dual


I've used the program "mesh2dual" in order to obtain a graph from an unstructured mesh.
I'd like to answer you if a program that give me also the information about the interface between 2 adjacent triangles.
Infact, I need of 2 informations:
1. given a triangle T, I want the ID of the triangle S near to T (this information is given by the graph);
2. if S is near T, how are the nodes of the corresponding interface?

Thank you!

RE: This information is not

This information is not provided. However, since you have access to the source code you can in principle modify it to get this information out. Or, you can just right a program to find for each pair of triangle connected by an edge their common nodes.
