Dear Bill and Amber user
The purpose of my dynamics is checking the sugar solubility in ionic liquid
by various method.
Ionic liquid has poor sugar solubility. But when I use water-mediated
method(mentioned previous mail), sugar solubility in ionic liquid has been
increased. This method has proven to be useful by real experiment. So I'd
like to know why solubility has been increased when using water
mediated-method by MD
Are there any method to mimic this procedure?
How about "Strip" command in PTRAJ? Does it affect the sugar molecules like
real evaporation?
Thank you as always
Regards,
Hoshin Kim.

No. Probably what you need to do is run a separate simulation without water.
An alternative would be to run without a periodic boundary (vacuum) and see
if the waters 'evaporate' into the void.
It might help if you state what you are trying to learn.
