[gmx-users] ion jumping out of water box

[גדעון לפידות]

Hi all,
I have been running simulations of a soluble protein bound to a pair of
calcium ions. I have been running this simulation in 4 nano second
intervals. everything looks fine until the 14th nano second when one of the
ions just jumps out of the water box. pbc-mol does not correct the problem.
I am using gromac version 4.0.7,
Does anyone know what the problem could be?
Thanks,
Gidoen
