Download an executable for Windows
|
|
----------------------------------
|
|
|
|
Pre-compiled Windows installers which install LAMMPS executables on a
|
|
Windows system can be downloaded from this site:
|
|
|
|
.. parsed-literal::
|
|
|
|
`https://packages.lammps.org/windows.html <https://packages.lammps.org/windows.html>`_
|
|
|
|
Note that each installer package has a date in its name, which
|
|
corresponds to the LAMMPS version of the same date. Installers for
|
|
current and older versions of LAMMPS are available. 32-bit and 64-bit
|
|
installers are available, and each installer contains both a serial
|
|
and parallel executable. The installer website also explains how to
|
|
install the Windows MPI package (MPICH2 from Argonne National Labs),
|
|
needed to run in parallel with MPI.
|
|
|
|
The LAMMPS binaries contain *all* :doc:`optional packages <Packages>`
|
|
included in the source distribution except: ADIOS, H5MD, KIM, ML-PACE,
|
|
ML-QUIP, MSCG, NETCDF, QMMM, SCAFACOS, and VTK. The serial version also
|
|
does not include the LATBOLTZ package. The PYTHON package is only
|
|
available in the Python installers that bundle a Python runtime. The
|
|
GPU package is compiled for OpenCL with mixed precision kernels.
|
|
|
|
The LAMMPS library is compiled as a shared library and the
|
|
:doc:`LAMMPS Python module <Python_module>` is installed, so that
|
|
it is possible to load LAMMPS into a Python interpreter.
|
|
|
|
The installer site also has instructions on how to run LAMMPS under
|
|
Windows, once it is installed, in both serial and parallel.
|
|
|
|
When you download the installer package, you run it on your Windows
|
|
machine. It will then prompt you with a dialog, where you can choose
|
|
the installation directory, unpack and copy several executables,
|
|
potential files, documentation PDFs, selected example files, etc. It
|
|
will then update a few system settings (e.g. ``PATH``, ``LAMMPS_POTENTIALS``)
|
|
and add an entry into the Start Menu (with references to the
|
|
documentation, LAMMPS homepage and more). From that menu, there is
|
|
also a link to an uninstaller that removes the files and undoes the
|
|
environment manipulations.
|
|
|
|
Note that to update to a newer version of LAMMPS, you should typically
|
|
uninstall the version you currently have, download a new installer, and
|
|
go through the installation procedure described above. I.e. the same
|
|
procedure for installing/updating most Windows programs. You can
|
|
install multiple versions of LAMMPS (in different directories), but only
|
|
the executable for the last-installed package will be found
|
|
automatically, so this should only be done for debugging purposes.
