Dear all,
I’ve found many discussions about the subject in the mail list. However I have not enough confidence about my setting yet. Please just have a look about them. Thanks.
In fact the z-cylinder wall just describes a system that no period in xy-plane (round boundary) but z-axis. To the special case, several parameters will be related in the lammps:
dimension 3
boundary f f p
fix npt GB npt/asphere 0.8 0.8 0.1 aniso NULL NULL NULL NULL 2 2 20 dilate partial.
Whether we only need to just adjust the pressure for z ? And to realize such adjustment we need using “aniso” to and setting NULL to xy? Is there any fault in the setting above? Thanks in advance!
