Hi Mark,
I am using Gromacs v.2018.x and as I tested it is not the matter of using
GPU or CPU.
The issue was from my side where by mistake I had put the wall (in all
posre.x,y,z.itp) exactly on the outer box borders so that my inner box and
outer box were fully identical,
so the molecules had no l
Hi,
It's certainly conceivable that such restraints are ineffective in some run
modes. However, "on the GPU" describes a range of scenarios. If you're
running with 2019.x, does adding -bonded cpu to the mdrun command line
restore the functionality?
Otherwise, please try the "working CPU" run on a

If the flat bottom restraint energy is zero, then that means that the
restraints aren't being applied, or your predefined distance is not being
exceeded. I doubt you would get binary zero values if it was the second
option, so something is probably wrong with your syntax or your inclusion
of the r
You may want to consider using smart-bottom restraints instead?
Jokes aside, why does it matter if your molecules move into the next
periodic image?
Cheers,
Billy

Any comment, please?
Thank you.

Hi Mark,
Thank you for your response.
Here are the part of options that gmx energy gives me out:
9 Coulomb-(SR)10 Coul.-recip.

Hi,
The total potential energy violating the restraints is reported, so you
should see that there is an appropriate contribution there, and probably
plan to stiffen the force constant.

Dear all,
Using the flat-bottom (K=4184 KJ/(mol. nm^2)) restrain I tried to have a
smaller cubic box as semi-preamble walls inside a bigger cubic box so that
all molecules except water would stay inside the smaller box during the
simulation, however, the wall doesn't work and the molecules are also
