2.2. Download an executable for Mac¶
LAMMPS can be downloaded, built, and configured for OS X on a Mac with Homebrew. (Alternatively, see the install instructions for Download an executable via Conda.) The following LAMMPS packages are unavailable at this time because of additional needs not yet met: GPU, KOKKOS, LATTE, MSCG, MPIIO, POEMS, VORONOI.
After installing Homebrew, you can install LAMMPS on your system with the following commands:
% brew install lammps
This will install the executables “lammps_serial” and “lammps_mpi”, as well as the LAMMPS “doc”, “potentials”, “tools”, “bench”, and “examples” directories.
Once LAMMPS is installed, you can test the installation with the Lennard-Jones benchmark file:
% brew test lammps -v
The LAMMPS binary is built with the KIM package which results in Homebrew also installing the kim-api binaries when LAMMPS is installed. In order to use potentials from openkim.org, you can install the openkim-models package
% brew install openkim-models
If you have problems with the installation you can post issues to this link.
Thanks to Derek Thomas (derekt at cello.t.u-tokyo.ac.jp) for setting up the Homebrew capability.
