Is it possible to implement a pressure ramp during the course of simulation in GROMACs akin to how a starting and ending pressure can be set using fix npt in LAMMPS?
There is no such feature in GROMACS, though it has been requested before. It’s on a developer to-do list, though probably low priority relative to other things. If someone wants to write the code and contribute it, that would speed up inclusion of the feature.
Thank you for the clarification!
