So if it were not quite clearly :) my main question is about methodology of such gradually temperature rise in the nvt enssemble conditions. Might it be realised by means of simple equilibation in one mdp file varying some parametries to change time-step of temperature growth? Or this methodology require several mdp files with slightly different ref_t as well as gen_temp options ? Finally what exactly is tau_t time constant?
