Hi all of the reaserchers
i have created some interstitial atoms using lammps code, but i can not use porosity option of the lammps properly. because i want just delete some number of interstitial atoms (not all atoms) randomly. "delete_atoms porosity..." delete all atoms (both interstitial and host atoms)and "delete_atoms group..." delete all the atom of the an atom type (not a fraction of them). does anyone know what is the solution?
thanks alot
I can suggest to write a simple script (e.g. in Python) that would generate your lattice manually. This method would allow you to prepare any system you need. Afterwards just make your simulations starting with the "read_data" command.
thank you Mr. Pokatashkin for your kind answer. perhaps this approach be a little annoying, although as the last alternate. Mr/Mrs Thompson suggested an approach in:
http://lammps.sandia.gov/threads/msg60527.html
but i wonder how we can use porosity as i mentioned?
You can identify the atom's location and ID in OVITO and then go to the dump file and delete that atom's values (one or few lines) and update the number of atoms left in the dump file, save and exit. You can read_dump and check if those atoms are deleted.
Thank you Mr.Arumugakani for your kind answering. This is a very interesting approach to do.
