[lammps-users] How to include atoms into an existing model?

Dear Lammps_users

    I have some problems on integrating two models together.
      The first model is read from a data file, and I want to
      include some other atoms (eg. create_atoms) with different force field into the system.
      (A "pair_style hybrid" calculation are expected to be implemented. )

      How to set pair_style for the new atoms? Does it affect the existing model?
      Is there some tips there?
   
      Any suggestion will be appreciated.
         

Best Regards

Zhenyu,

Yes, what you intend to do can very likely be done with LAMMPS. To
learn how to use pair_style hybrid, see this and related pages:

http://lammps.sandia.gov/doc/pair_hybrid.html

You must tell LAMMPS how each atom type should interact with every
other atom type.
