[gmx-users] pressure coupling without pbc

[MURAT OZTURK]

Hello,

I have read somewhere in the list that I cannot do pressure coupling
without pbc.

What I essentially need is a box with impermeable walls, that get smaller
as the simulation proceeds.

I do anisotropic pressure coupling with two impermeable walls (in xy axis)
for another simulation, and it works.

I basically need 4 more walls and isotropic pressure coupling, is this
entirely impossible in GROMACS?

Thanks,

Murat
