Hello everyone,

I am trying to simulate the confined water between two graphene sheets in GCMC ensemble. I knew how to create the MCF file for water but I don't have any Idea to make the MCF file for graphene sheets. should I create another box for each graphene sheet?
Should I only use the unit cell of graphene in order to make a pdb file?
I would appreciate if anybody can help me.

Thank you,
Neda

Hi Neda,

Rigid solid surfaces are not supported in Cassandra 1.0, but will be supported in Cassandra 1.1 -- to be released in the coming weeks.

Cheers,
Ryan

Hi Ryan,
Did you put any example for Rigid solid surfaces in a new version of Cassandra? I am still having a problem to create graphene surfaces. Could you please give me some hints?
Thanks, Neda

Hi Neda,

There are several examples of simulating various fluids within a rigid model of silicalite. You can find the examples in the Examples/GCMC directory. Each of these examples begins with an empty zeolite. During the course of the simulation, fluid phase molecules (e.g. methane, butane, nitrogen) are inserted according to the chemical potential set point.

See Ch 6 of the user guide for information on what files you will need to simulate water between sheets of graphene.

Do you have a configuration file listing your graphene atom coordinates?

I was able to get a test system of water between graphite sheets working. Have you made any progress yet?

Thanks for your reply. No, I am still working on it.
before I started MC, I was working in MD. I made the configuration with VMD and I used Lammps and I didn't have any problem. But now I am confused. How can I add graphite sheets to my system?
Should I use the new box system?1 box for water and 1 box for graphite sheets?
Or I should use fragment and built graphite sheet and then use the fragment in my main script.
I am still reading Ch6 and working on examples to understand.
Please help me in this part.
Thanks, Neda
