In gromacs you can not calculate h-bond life time. You can use mdanalysis tool for calculating h-bond lifetime. On Tue 14 May, 2019, 11:56 AM , wrote: > Then what is the right way to calculate lifetime of a hydrogen bond? > - Message from Bratin Kumar Das <177cy500.bra...@nitk.edu.in> >

[gmx-users] Calculate Young''s modulus using NPT and anisotropic

2019-05-14 Thread veerapandian
Dear GROMACS members, I would like to calculate the Young's modulus for crystalline cellulose. I simulate the system using NPT ensemble with anisotropic barostat. I apply a constant stress in a given direction. For instance, I apply a constant stress in XX direction and set the compressability

Hi In md analysis you can calculate continuous h-bond. That will give you proper lifetime. On Tue 14 May, 2019, 11:58 AM Bratin Kumar Das, <177cy500.bra...@nitk.edu.in> wrote: > In gromacs you can not calculate h-bond life time. You can use mdanalysis > tool for calculating h-bond lifetime.
