[gmx-users] equilibrium state

Dear GROMACS Specialists, We know that one system is at equilibrium state when the variation of Helmholtz or Gibbs free energy be zero. May I ask you say me that how I can understand that my system has reached to equilibrium state in the end of simulation, Please? Best Regards Sara -- gmx-user
