How to generate FENE bead/spring chains from all-atom model

Dear Everyone,

I have built an all-atom model for my polymers in Material Studio. And I have done several different deformation tests in Lammps at atomistic level using "atom_style full ".
Now I want to work on "FENE bead/spring chains " model for the polymers.

I don’t know how to build FENE bead/spring chains based on the all-atom model I have from Material Studio. Is there any utility or method to do this transformation?

Thank you for any comments,

Best regards,

Create polyethylene molecule of desired length
Select all hydrogen atoms.
Delete all hydrogen atoms

You have a bead spring model :slight_smile: Enjoy
