Hi Jelle, Thanks for quick reply.
Yes, I am talking about FEM meshing. May I re-explain my question. I have a big modeling, I have meshed it already. What I want right now is: only to get the nodes index of one end of the partial modeling (just the node on one edge). I am wondering is there any commands to get the specific edge index and the nodes index belonging to that edge, after meshing?
