I have a question about modeling a Graphen sheet or Nano tube in Abaqus.
I design a Graphen in VMD Software or Nanotube Builder. when I save the coordinates of carbon atoms, they gave me a file with .pdb format.
then I shoud import it to abaqus and make beams between the coordinates and analyse it.

How can I do this job? I think I should use Python or Matlab to convert .pdb file to .inp ...
please help me if you can.
or if you have this Python code Or Matlab Code please Send me.
