[gmx-users] Weird configuration when pulling rate is small

[Erik Marklund]

Dear Ming,

Sounds like a visualisation problem. Does it persist if you e.g. translate the system with trjconv?

Kind regards,
Erik

However, when I decrease the pulling rate to 0.0002 nm/ps or lower, the configuration is messy (some atoms flow away from the triple helix), but the simulations run well and both the force_strain curve and the history of number of h_bonds  look normal. Could anybody tell me why is that low pulling rates cause this problem?
