Dear all In pull code simulation i want pull my system with constant force pulling in both direction. In the below i applied a position restrain at group 1 and pull with constant force the outher group. but know i want apply constant force pulling in both direction. I want your suggestion how should I change the below code.
; Pull code pull = yes pull_ngroups = 2 pull_ncoords = 1 pull_group1_name = Pos_B pull_group2_name = Pos_A pull_coord1_type = constant-force ; harmonic biasing force pull_coord1_geometry = distance ; simple distance increase pull_coord1_groups = 1 2 pull_coord1_dim = N N Y pull_coord1_k = -7000 ; kJ mol^-1 nm^-1 pull_coord1_start = yes ; define initial COM distance > 0 -- *Md Imrul Reza Shishir* Master Student *Inha University* *CRC for NanoCellulose Future Composites* 36 Getbeol-ro, Yeonsu-gu Incheon 21999 South Korea -- Gromacs Users mailing list * Please search the archive at http://www.gromacs.org/Support/Mailing_Lists/GMX-Users_List before posting! * Can't post?
