Hi,<br><br>Is the c.o.m. velocity a conserved quantity in NVT dynamics?<br>For example, if the c.o.m. velocity is initially zero should it stay that way for the rest of the simulation?<br><br>Would a larger system be more susceptible to "forces" introduced by a finite tolerance
<br>on the SCF cycle?<br><br>If anyone on the list has experience with such things, it would be helpful.<br><br>-- <br>Nichols A. Romero, Ph.D.<br>1613 Denise Dr. Apt. D<br>Forest Hill, MD 21050<br>443-567-8328 (C)<br>410-306-0709 (O)
