Nagoya Atomistic-simulation Package (nap) includes the following programs and utilities:

• parallel molecular dynamics simulation (pmd)
• potential parameter fitting (fitpot for neural-network potential, and for other potentials, see optzer)
• python modules for pre/post-processes (nappy)

The program, pmd, includes various interatomic potentials for metals and semiconductors, and uses spatial decomposition technique for the parallelization, and linked-cell method for efficient neighbor search.

• Ryo KOBAYASHI
• Assistant Professor in the department of mechanical engineering, Nagoya Institute of Technology.

To compile pmd and fitpot, the following programs/libraries are required:

• Fortran compiler
• MPI library

nappy requires the following packages:

• numpy
• scipy
• pandas
• docopt
• ASE

For the short test, whether or not you can use this program in your environment,

$ git clone https://github.com/ryokbys/nap.git ./nap
$ cd nap/
$ ./configure --prefix=$(pwd)
$ make test

If it works, you can use this program in your system. To install the python package nappy,

$ python setup.py sdist
$ pip install -e .

Then you can use the nappy commands, napsys, in the terminal and can import nappy package in python programs.
