Dear Gromacs Users, I am trying to learn viscosity calculations using non-equilibrium method in Gromacs 4.5.4. I have gone through Hess paper and several posts on viscosity calculation. I have setup a system of pure water (32000 molecules) and run till 10 ns using NPT and setting cos-acceleration=

Hello, I am trying to calculate the viscosity of my pure water system at 275K. The system has run for 40ns. I issued the following command: g_energy_d_mpi -f 275K_50_50_50_2.edr -s 275K_50_50_50_2.tpr -nmol 4202 -vis sixsitewater_275K -b 0 -e 4 The numbers I get in the output file are
