Iam looking for a united atom model initial chain. And also once one chain is made , what is the best way to proceed to make the initial configuration of the system?( I usually make duplicates, put them all in the box together and apply some repulsive potential to introduce excluded volume but that takes quite a while)? Thanks Vani
