How to run LAMMPS on Mac
1. INSTALL
Show 2. RUNLet’s try with an example file: a colloid case in ~/examples/.
The visualization movie could be obtained here (lammps.org). One frame of the movie (Colloids put in a background solvent of Lennard-Jones particles)LAMMPS Installation Installation in windows Installation in Ubuntu and other LINUX systems 2.

Go to the directory where you have your input script by using "cd" command in command prompt 3. Type "lmp_serial.exe Running LAMMPS in Linux and Mac 1. Open terminal 2. Go to "LAMMPS_test_run" folder by using "cd" command in the terminal 3. Type "lmp_serial -in inputscript.in" and press enter (replace "inputscript.in" with input file
name. Your input file can be in ".in" or ".txt" format). So these are the steps for installation and running of LAMMPS. If you have any difficulty do mention in comment session or contact me through E-Mail. It’s very easy to start molecular dynamics (MD) on Mac. Contents Molecular dynamics (MD) is a computer simulation method for studying the physical movements of atoms and molecules. We can simulate the energy or motion of atoms by molecular dynamics (MD). An atom is too small to see it directly. However, we can observe an atom, its motion, reaction and so on, via MD. Recently, we can use MD very easily. LAMMPS is a molecular dynamics software and is free. We can use Lammps.

Where is LAMMPS located?The source files of the LAMMPS code are found in two directories of the distribution: src and lib . Most of the code is written in C++ but there are small a number of files in several other languages like C, Fortran, Shell script, or Python. The core of the code is located in the src folder and its sub-directories.
How do I run a LAMMPS script in Linux?You normally run the LAMMPS command in the directory where your input script is located. That is also where output files are produced by default, unless you provide specific other paths in your input script or on the command line. As in some of the examples above, the LAMMPS executable itself can be placed elsewhere.
