amorphous polymer


I want to generate starting coordinates of an amorphous polymer. I would like to know if there is any utility that does the job or I need to write my own code to do it ?

If no free utility is available, can someone help me with some relevant references ?



The chain tool in the LAMMPS tools dir does it
for linear bead-spring chains. You then have
to equilibrate with a soft potential like pair soft.
