Searching for a way to stimulate glutamate molecule

Hi I’m new in lammps I need to stimulate glutamate molecule but I don’t know how and where can I start?

To stimulate a molecule, you likely need electromagnetic radiation.

To simulate a molecule, you must ditch the forum and start reading the HowTo section of the LAMMPS manual, plus a relevant example from the many shipped with the source code. Do not expect a tutoring service, which is the duty of your supervisor or colleagues.
