Coarsw grain model of polymer

[Runak_R]

Dear lammps users,

I have two main questions. Firstly, is there any example for drug release, I mean prepared LAMMPS code. Secondly, I have a question about simulating polymers, I have a problem in understanding polymer simulation using coarse grain method. What is the main difference between coarse grain and all atom methods in practice? How the potential parameters of the coarse grain method is determined?

Best regards,
Runak

This is far too generic a description.

This is a subject for looking up text books and related publications or review articles that describe the various approaches and their applications, benefits, and shortcomings.
