[gmx-users] High Temprature MD with scaled params

I have scaled the non-bonded parameters(charges and epsilon) of tip3p atoms
in ffnonbonded.itp file(charmm forcefield). They are scaled by a ratio of
3/5. The simulation is then run at 500K for the protein water system. The
temperature exploded after first 20 steps. This does not happen if I run the
simulations with the unscaled parameters. I have also tried this with T=400
and temperature remains stable.
Quaerendo Invenietis-Seek and you shall discover.
