[gmx-users] Amorphous polymer and periodic box

Dear All

There are some initial steps for MD simulation of Amorphous polymer:

1-The periodic box,which is usually cubic are chosen

2-Then chain propagation takes place.As the chain propagates out of the 
periodic box through one face,it enters the box through the opposite 
face.Replication of the box thus produces correctly covalently connected 

therefore,I can't accommodate some chain polymer in a (periodicc )box 

Can gromacs do it(second step)?

Sincerely yours
