[gmx-users] NVE simulation and pressure scaling in one dimension and constant size simulation in another.

[zhongjin]

Hi all,
    I want to know how to set a NVE simulation ? Now I can do a NVT or NPT simulation.
    How to realize pressure scaling in one dimension and constant size simulation in another? For example,the simulation box size in the z-direction was adjusted to maintain the constant pressure, while the box size in xy-directions was constant. Should I set compressibility = 0 in the xy-direction or set tau-p = 0 in the xy-direction, or ref-p = 0 in the xy-direction ? Thanks !
