[gmx-users] deformation in cnt

2013-12-11 Thread Atila Petrosian
Dear Justin Thanks for your reply. After energy minimization, all carbon atoms are in true position, inside box but again, both ends of cnt were deformed, same problem I had before I add bond length to the length of CNT in z dimension of box. You mentioned possibly poor input geometry . Please

Dear Justin I built CNT by nano tube modeller. Then, I put protein (fragment model with 15 residues) in appropriate distance of CNT manually. I used force field parameters from following paper: J. Phys. Chem. B 2001, 105, 9980-9987. -- Gromacs Users mailing list * Please search the archive at

If the system does not explode, everything is correct. Though your solution is perhaps in the wrong place in relation to the tube. Dr. Vitaly V. Chaban On Tue, Dec 10, 2013 at 10:02 AM, Atila Petrosian atila.petros...@gmail.com wrote: Dear Justin Based on your suggestion, I added C-C bond
