Title: how to insert a nano tube in to a amorphous cell
Post by: DR.HARSHA on January 16, 2017, 19:19
i want to insert a nano tube in to an amorphous cell like the image displayed is it possible in VNL to do it. If not what options do i have to achieve this task.
please see the attachment.
thank you

Yes, it is possible to set up the system you describe using VNL, at least if you know the nature of the polymer. However, the best approach depends on what kind of calculations you want to run, so we can be of more help if you shed some light on this.

I assume you would like to place it in one of the channels running in the A-direction, currently occupied by the benzene?

In that case, I would do the following:


You now have the premade CNT inside the channel in the polymer, but note that it does not necessarily fit with the periodicity of the polymer bulk.

You need to be more specific than that. Exactly what is not working? What did you try, what happened?
