I have a question about fixing graphene oxide sheet for simulation with gromacs
I used three methods to MD Simulation of graphene oxide, but unfortunately, in the next stage, I encountered problems with nvt and npt step.
In the first method, I used the strong position restrained and used the command, however, I encountered the collapse of the graphene oxide sheets.
In the second method, I used the option of freezing and fixing the graphene oxide screen and modified the parameters related to mdp file, in which case I should have used the group algorithm instead of verlet, which is obsolete according to the new versions of Gromacs.
In the third method, I used the method of setting non-banded parameters to zero, which was mentioned in the articles, but again, the results were not acceptable.
Thank you for helping me if you have experience in this field.
