VMD has a nanotube builder that I can use to build CNT and then using topotools I am able to produce the data file for LAMMPS. For my specific research I need to create a fake CNT with triangular lattice instead of hegxagonal. I can create that with mathematica but it explodes and I guess it is because I do not have the dihedral and other angle informations.
My question is if you know of any (preferably free) software that I can use to create my own specific lattice shape nanotube and get the data file as an output?
Thank you so much
