Hi experts,
I'm getting some strange behavior when simulating tip4p water using a
thermostat. If I simulate without langevin, the water diffuses really fast,
what is expectable. When using langevin, the water seem to compress a little
and then sticks together as a whole bunch. There are long chains of the
dummy atoms to hydrogens.
It looks like the dummy atoms have very strong charges, or is this a usual
behavior?
Any ideas?
Thanks in advance
Norman Geist.
