[gmx-users] Temperature coupling

Still about the question of temperature coupling with method of the periodic perturbation I have the following question: Only the y and z components are rescaled in the temperature coupling? Original Post: " I am trying to calculate the viscosity of water (spc model) by periodic perturbation meth

Vitaly V. Chaban, this is the question. How to remove the heat generated by viscous friction by heat bath without coupling the velocity profile to heat bath? Also, why to remove the velocity profile of the kinetic energy? On Sat, Feb 22, 2014 at 9:08 PM, Marcelo Vanean wrote: > Michael Shi

Michael Shirts, in this article is not discussed about the periodic perturbation method to calculate viscosity. Anyway, thank you. On Sat, Feb 22, 2014 at 7:16 PM, Marcelo Vanean wrote: > Dr. Vitaly Chaban, I know that g_energy is doing all the work for me. > However I want to understa

Dr. Vitaly Chaban, I know that g_energy is doing all the work for me. However I want to understand the concepts. On Fri, Feb 21, 2014 at 6:38 PM, Marcelo Vanean wrote: > I am trying to calculate the viscosity of water (spc model) by periodic > perturbation method. The manual says (

I am trying to calculate the viscosity of water (spc model) by periodic perturbation method. The manual says (manual 4.6.5, pages 169 - 170): "To obtain the correct value for the viscosity the generated velocity profile should not be coupled to the heat bath, also the velocity profile should be exc
