Sender: Johan Postma <POSTMA@EMBL-Heidelberg.DE> Subject: Re: WSN: Constant pressure i have had no experience with the TIP3P potential.. but did extensive simulations with the SPC water potential (>25 PS) and did not obsereve this behaviour. We saw a more oscilating behaviour of the volume but did not analyze this further. Are you sure the temperature etc.. is correct.?? johan postma EMBL Heidelberg Germany
