# Version Updates
LAMMPS follows continuous release development model. We aim to keep all
release versions (stable or patch) fully functional and employ a variety
of automatic testing procedures to detect failures of existing
functionality from adding new features before releases are made. Thus
bugfixes and updates are only integrated into the current development
branch and thus the next (patch) release and users are recommended to
update regularly.
LAMMPS follows continuous release development model. We aim to keep to
keep the development version (develop branch) always fully functional
and employ a variety of automatic testing procedures to detect failures
of existing functionality from adding or modifying features. Most of
those tests are run on pull requests *before* merging to the development
branch. The develop branch is protected, so all changes *must* be
submitted as a pull request and thus cannot avoid the automated tests.
Additional tests are run *after* merging. Before releases are made
*all* tests must have cleared. Then a release tag is applied and the
release branch fast-forwarded to that tag. Bug fixes and updates are
applied to the current development branch and thus will be available in
the next (patch) release. For stable releases, selected bug fixes are
back-ported and occasionally published as update releases. There are
only updates to the latest stable release.

.. admonition:: Software version requirements for testing
:class: note
The compiler and library version requirements for the testing
framework are more strict than for the main part of LAMMPS. For
example the default GNU C++ and Fortran compilers of RHEL/CentOS 7.x
(version 4.8.x) are not sufficient. The CMake configuration will try
to detect compatible versions and either skip incompatible tests or
stop with an error.
After compilation is complete, the unit testing is started in the build
folder using the ``ctest`` command, which is part of the CMake software.
The output of this command will be looking something like this::

Notes for updating code written for older LAMMPS versions
---------------------------------------------------------
This section documents how C++ source files that are available *outside
of the LAMMPS source distribution* (e.g. in external USER packages or as
source files provided as a supplement to a publication) that are written
for an older version of LAMMPS and thus need to be updated to be
compatible with the current version of LAMMPS. Due to the active
development of LAMMPS it is likely to always be incomplete. Please
contact developers@lammps.org in case you run across an issue that is not
(yet) listed here. Please also review the latest information about the
LAMMPS :doc:`programming style conventions <Modify_style>`, especially
if you are considering to submit the updated version for inclusion into
the LAMMPS distribution.
Available topics in mostly chronological order are:
- `Setting flags in the constructor`_
- `Rename of pack/unpack_comm() to pack/unpack_forward_comm()`_
- `Use ev_init() to initialize variables derived from eflag and vflag`_
- `Use utils::numeric() functions instead of force->numeric()`_
- `Use utils::open_potential() function to open potential files`_
- `Simplify customized error messages`_
- `Use of "override" instead of "virtual"`_
- `Simplified and more compact neighbor list requests`_
- `Split of fix STORE into fix STORE/GLOBAL and fix STORE/PERATOM`_
- `Use Output::get_dump_by_id() instead of Output::find_dump()`_
----
Setting flags in the constructor
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
As LAMMPS gains additional functionality, new flags may need to be set
in the constructor or a class to signal compatibility with such features.
Most of the time the defaults are chosen conservatively, but sometimes
the conservative choice is the uncommon choice, and then those settings
need to be made when updating code.
Pair styles:
- ``manybody_flag``: set to 1 if your pair style is not pair-wise additive
- ``restartinfo``: set to 0 if your pair style does not store data in restart files
Rename of pack/unpack_comm() to pack/unpack_forward_comm()
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. versionchanged:: 8Aug2014
In this change set the functions to pack data into communication buffers
and to unpack data from communication buffers for :doc:`forward
communications <Developer_comm_ops>` were renamed from ``pack_comm()``
and ``unpack_comm()`` to ``pack_forward_comm()`` and
``unpack_forward_comm()``, respectively. Also the meaning of the return
value of these functions was changed: rather than returning the number
of items per atom stored in the buffer, now the total number of items
added (or unpacked) needs to be returned. Here is an example from the
`PairEAM` class. Of course the member function declaration in corresponding
header file needs to be updated accordingly.
Old:
.. code-block:: C++
int PairEAM::pack_comm(int n, int *list, double *buf, int pbc_flag, int *pbc)
{
int m = 0;
for (int i = 0; i < n; i++) {
int j = list[i];
buf[m++] = fp[j];
}
return 1;
}
New:
.. code-block:: C++
int PairEAM::pack_forward_comm(int n, int *list, double *buf, int pbc_flag, int *pbc)
{
int m = 0;
for (int i = 0; i < n; i++) {
int j = list[i];
buf[m++] = fp[j];
}
return m;
}
.. note::
Because the various "pack" and "unpack" functions are defined in the
respective base classes as dummy functions doing nothing, and because
of the the name mismatch the custom versions in the derived class
will no longer be called, there will be no compilation error when
this change is not applied. Only calculations will suddenly produce
incorrect results because the required forward communication calls
will cease to function correctly.
Use ev_init() to initialize variables derived from eflag and vflag
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. versionchanged:: 29Mar2019
There are several variables that need to be initialized based on
the values of the "eflag" and "vflag" variables and since sometimes
there are new bits added and new variables need to be set to 1 or 0.
To make this consistent, across all styles, there is now an inline
function ``ev_init(eflag, vflag)`` that makes those settings
consistently and calls either ``ev_setup()`` or ``ev_unset()``.
Example from a pair style:
Old:
.. code-block:: C++
if (eflag || vflag) ev_setup(eflag, vflag);
else evflag = vflag_fdotr = eflag_global = eflag_atom = 0;
New:
.. code-block:: C++
ev_init(eflag, vflag);
Not applying this change will not cause a compilation error, but
can lead to inconsistent behavior and incorrect tallying of
energy or virial.
Use utils::numeric() functions instead of force->numeric()
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. versionchanged:: 18Sep2020
The "numeric()" conversion functions (including "inumeric()",
"bnumeric()", and "tnumeric()") have been moved from the Force class to
the utils namespace. Also they take an additional argument that selects
whether the ``Error::all()`` or ``Error::one()`` function should be
called in case of an error. The former should be used when *all* MPI
processes call the conversion function and the latter *must* be used
when they are called from only one or a subset of the MPI processes.
Old:
.. code-block:: C++
val = force->numeric(FLERR, arg[1]);
num = force->inumeric(FLERR, arg[2]);
New:
.. code-block:: C++
val = utils::numeric(FLERR, true, arg[1], lmp);
num = utils::inumeric(FLERR, false, arg[2], lmp);
.. seealso::
:cpp:func:`utils::numeric() <LAMMPS_NS::utils::numeric>`,
:cpp:func:`utils::inumeric() <LAMMPS_NS::utils::inumeric>`,
:cpp:func:`utils::bnumeric() <LAMMPS_NS::utils::bnumeric>`,
:cpp:func:`utils::tnumeric() <LAMMPS_NS::utils::tnumeric>`
Use utils::open_potential() function to open potential files
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. versionchanged:: 18Sep2020
The :cpp:func:`utils::open_potential()
<LAMMPS_NS::utils::open_potential>` function must be used to replace
calls to ``force->open_potential()`` and should be used to replace
``fopen()`` for opening potential files for reading. The custom
function does three additional steps compared to ``fopen()``: 1) it will
try to parse the ``UNITS:`` and ``DATE:`` metadata will stop with an
error on a units mismatch and will print the date info, if present, in
the log file; 2) for pair styles that support it, it will set up
possible automatic unit conversions based on the embedded unit
information and LAMMPS' current units setting; 3) it will not only try
to open a potential file at the given path, but will also search in the
folders listed in the ``LAMMPS_POTENTIALS`` environment variable. This
allows to keep potential files in a common location instead of having to
copy them around for simulations.
Old:
.. code-block:: C++
fp = force->open_potential(filename);
fp = fopen(filename, "r");
New:
.. code-block:: C++
fp = utils::open_potential(filename, lmp);
Simplify customized error messages
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. versionchanged:: 14May2021
Aided by features of the bundled {fmt} library, error messages now
can have a variable number of arguments and the string will be interpreted
as a {fmt} style format string so that custom error messages can be
easily customized without having to use temporary buffers and ``sprintf()``.
Example:
Old:
.. code-block:: C++
if (fptr == NULL) {
char str[128];
sprintf(str,"Cannot open AEAM potential file %s",filename);
error->one(FLERR,str);
}
New:
.. code-block:: C++
if (fptr == nullptr)
error->one(FLERR, "Cannot open AEAM potential file {}: {}", filename, utils::getsyserror());
Use of "override" instead of "virtual"
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. versionchanged:: 17Feb2022
Since LAMMPS requires C++11 we switched to use the "override" keyword
instead of "virtual" to indicate polymorphism in derived classes. This
allows the C++ compiler to better detect inconsistencies when an
override is intended or not. Please note that "override" has to be
added to **all** polymorph functions in derived classes and "virtual"
*only* to the function in the base class (or the destructor). Here is
an example from the ``FixWallReflect`` class:
Old:
.. code-block:: C++
FixWallReflect(class LAMMPS *, int, char **);
virtual ~FixWallReflect();
int setmask();
void init();
void post_integrate();
New:
.. code-block:: C++
FixWallReflect(class LAMMPS *, int, char **);
~FixWallReflect() override;
int setmask() override;
void init() override;
void post_integrate() override;
This change set will neither cause a compilation failure, nor will it
change functionality, but if you plan to submit the updated code for
inclusion into the LAMMPS distribution, it will be requested for achieve
a consistent :doc:`programming style <Modify_style>`.
Simplified function names for forward and reverse communication
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. versionchanged:: 24Mar2022
Rather then using the function name to distinguish between the different
forward and reverse communication functions for styles, LAMMPS now uses
the type of the "this" pointer argument.
Old:
.. code-block:: C++
comm->forward_comm_pair(this);
comm->forward_comm_fix(this);
comm->forward_comm_compute(this);
comm->forward_comm_dump(this);
comm->reverse_comm_pair(this);
comm->reverse_comm_fix(this);
comm->reverse_comm_compute(this);
comm->reverse_comm_dump(this);
New:
.. code-block:: C++
comm->forward_comm(this);
comm->reverse_comm(this);
This change is **required** or else the code will not compile.
Simplified and more compact neighbor list requests
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. versionchanged:: 24Mar2022
This change set reduces the amount of code required to request a
neighbor list. It enforces consistency and no longer requires to change
internal data of the request. More information on neighbor list
requests can be :doc:`found here <Developer_notes>`. Example from the
``ComputeRDF`` class:
Old:
.. code-block:: C++
int irequest = neighbor->request(this,instance_me);
neighbor->requests[irequest]->pair = 0;
neighbor->requests[irequest]->compute = 1;
neighbor->requests[irequest]->occasional = 1;
if (cutflag) {
neighbor->requests[irequest]->cut = 1;
neighbor->requests[irequest]->cutoff = mycutneigh;
}
New:
.. code-block:: C++
auto req = neighbor->add_request(this, NeighConst::REQ_OCCASIONAL);
if (cutflag) req->set_cutoff(mycutneigh);
Public access to the ``NeighRequest`` class data members has been
removed so this update is **required** to avoid compilation failure.
Split of fix STORE into fix STORE/GLOBAL and fix STORE/PERATOM
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. versionchanged:: 15Sep2022
This change splits the GLOBAL and PERATOM modes of fix STORE into two
separate fixes STORE/GLOBAL and STORE/PERATOM. There was very little
shared code between the two fix STORE modes and the two different code
paths had to be prefixed with if statements. Furthermore, some flags
were used differently in the two modes leading to confusion. Splitting
the code into two fix styles, makes it more easily maintainable. Since
these are internal fixes, there is no user visible change.
Old:
.. code-block:: C++
#include "fix_store.h"
FixStore *fix = dynamic_cast<FixStore *>(
modify->add_fix(fmt::format("{} {} STORE peratom 1 13",id_pole,group->names[0]));
FixStore *fix = dynamic_cast<FixStore *>(modify->get_fix_by_id(id_pole));
New:
.. code-block:: C++
#include "fix_store_peratom.h"
FixStorePeratom *fix = dynamic_cast<FixStorePeratom *>(
modify->add_fix(fmt::format("{} {} STORE/PERATOM 1 13",id_pole,group->names[0]));
FixStorePeratom *fix = dynamic_cast<FixStorePeratom *>(modify->get_fix_by_id(id_pole));
Old:
.. code-block:: C++
#include "fix_store.h"
FixStore *fix = dynamic_cast<FixStore *>(
modify->add_fix(fmt::format("{} {} STORE global 1 1",id_fix,group->names[igroup]));
FixStore *fix = dynamic_cast<FixStore *>(modify->get_fix_by_id(id_fix));
New:
.. code-block:: C++
#include "fix_store_global.h"
FixStoreGlobal *fix = dynamic_cast<FixStoreGlobal *>(
modify->add_fix(fmt::format("{} {} STORE/GLOBAL 1 1",id_fix,group->names[igroup]));
FixStoreGlobal *fix = dynamic_cast<FixStoreGlobal *>(modify->get_fix_by_id(id_fix));
This change is **required** or else the code will not compile.
Use Output::get_dump_by_id() instead of Output::find_dump()
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. versionchanged:: 15Sep2022
The accessor function to individual dump style instances has been changed
from ``Output::find_dump()`` returning the index of the dump instance in
the list of dumps to ``Output::get_dump_by_id()`` returning a pointer to
the dump directly. Example:
Old:
.. code-block:: C++
int idump = output->find_dump(arg[iarg+1]);
if (idump < 0)
error->all(FLERR,"Dump ID in hyper command does not exist");
memory->grow(dumplist,ndump+1,"hyper:dumplist");
dumplist[ndump++] = idump;
[...]
if (dumpflag)
for (int idump = 0; idump < ndump; idump++)
output->dump[dumplist[idump]]->write();
New:
.. code-block:: C++
auto idump = output->get_dump_by_id(arg[iarg+1]);
if (!idump) error->all(FLERR,"Dump ID {} in hyper command does not exist", arg[iarg+1]);
dumplist.emplace_back(idump);
[...]
if (dumpflag) for (auto idump : dumplist) idump->write();
This change is **required** or else the code will not compile.

Type labels
===========
.. versionadded:: 15Sep2022
Each atom in LAMMPS has an associated numeric atom type. Similarly,
each bond, angle, dihedral, and improper is assigned a bond type,
angle type, and so on. The primary use of these types is to map
potential (force field) parameters to the interactions of the atom,
bond, angle, dihedral, and improper.
By default, type values are entered as integers from 1 to Ntypes
wherever they appear in LAMMPS input or output files. The total number
Ntypes for each interaction is "locked in" when the simulation box
is created.
A recent addition to LAMMPS is the option to use strings - referred
to as type labels - as an alternative. Using type labels instead of
numeric types can be advantageous in various scenarios. For example,
type labels can make inputs more readable and generic (i.e. usable through
the :doc:`include command <include>` for different systems with different
numerical values assigned to types. This generality also applies to
other inputs like data files read by :doc:`read_data <read_data>` or
molecule template files read by the :doc:`molecule <molecule>`
command. See below for a list of other commands that can use
type labels in different ways.
LAMMPS will *internally* continue to use numeric types, which means
that many previous restrictions still apply. For example, the total
number of types is locked in when creating the simulation box, and
potential parameters for each type must be provided even if not used
by any interactions.
A collection of type labels for all type-kinds (atom types, bond types,
etc.) is stored as a "label map" which is simply a list of numeric types
and their associated type labels. Within a type-kind, each type label
must be unique. It can be assigned to only one numeric type. To read
and write type labels to data files for a given type-kind, *all*
associated numeric types need have a type label assigned. Partial
maps can be saved with the :doc:`labelmap write <labelmap>` command
and read back with the :doc:`include <include>` command.
Valid type labels can contain most ASCII characters, but cannot start
with a number, a '#', or a '*'. Also, labels must not contain whitespace
characters. When using the :doc:`labelmap command <labelmap>` in the
LAMMPS input, if certain characters appear in the type label, such as
the single (') or double (") quote or the '#' character, the label
must be put in either double, single, or triple (""") quotes. Triple
quotes allow for the most generic type label strings, but they require
to have a leading and trailing blank space. When defining type labels
the blanks will be ignored. Example:
.. code-block:: LAMMPS
labelmap angle 1 """ C1'-C2"-C3# """
This command will map the string ```C1'-C2"-C3#``` to the angle type 1.
There are two ways to define label maps. One is via the :doc:`labelmap
<labelmap>` command. The other is via the :doc:`read_data <read_data>`
command. A data file can have sections such as *Atom Type Labels*, *Bond
Type Labels*, etc., which assign type labels to numeric types. The
label map can be written out to data files by the :doc:`write_data
<write_data>` command. This map is also written to and read from
restart files, by the :doc:`write_restart <write_restart>` and
:doc:`read_restart <read_restart>` commands.
----------
Use of type labels in LAMMPS input or output
""""""""""""""""""""""""""""""""""""""""""""
Many LAMMPS input script commands that take a numeric type as an
argument can use the associated type label instead. If a type label
is not defined for a particular numeric type, only its numeric type
can be used.
This example assigns labels to the atom types, and then uses the type
labels to redefine the pair coefficients.
.. code-block:: LAMMPS
pair_coeff 1 2 1.0 1.0 # numeric types
labelmap atom 1 C 2 H
pair_coeff C H 1.0 1.0 # type labels
Adding support for type labels to various commands is an ongoing
project. If an input script command (or a section in a file read by a
command) allows substituting a type label for a numeric type argument,
it will be explicitly mentioned in that command's documentation page.
As a temporary measure, input script commands can take advantage of
variables and how they can be expanded during processing of the input.
The variables can use functions that will translate type label strings
to their respective number as defined in the current label map. See the
:doc:`variable <variable>` command for details.
For example, here is how the pair_coeff command could be used with
type labels if it did not yet support them, either with an explicit
variable command or an implicit variable used in the pair_coeff
command.
.. code-block:: LAMMPS
labelmap atom 1 C 2 H
variable atom1 equal label2type(atom,C)
variable atom2 equal label2type(atom,H)
pair_coeff ${atom1} ${atom2} 1.0 1.0
.. code-block:: LAMMPS
labelmap atom 1 C 2 H
pair_coeff $(label2type(atom,C)) $(label2type(atom,H)) 80.0 1.2
----------
Commands that can use label types
"""""""""""""""""""""""""""""""""
Any workflow that involves reading multiple data files, molecule
templates or a combination of the two can be streamlined by using type
labels instead of numeric types, because types are automatically synced
between the files. The creation of simulation-ready reaction templates
for :doc:`fix bond/react <fix_bond_react>` is much simpler when using
type labels, and results in templates that can be used without
modification in multiple simulations or different systems.

A pre-built LAMMPS executable suitable for running on the latest
Ubuntu Linux versions, can be downloaded as a Debian package. This
allows you to install LAMMPS with a single command, and stay
up-to-date with the current stable version of LAMMPS by simply updating
your operating system. Please note, that the repository below offers
two LAMMPS packages, ``lammps-daily`` and ``lammps-stable``. The
LAMMPS developers recommend to use the ``lammps-stable`` package for
any production simulations. The ``lammps-daily`` package is built
from the LAMMPS development sources, and those versions may have known
issues and bugs when new features are added and the software has not
undergone full release testing.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Pre-built LAMMPS packages for stable releases are available
in the Fedora Linux distribution as of version 28. The packages
can be installed via the dnf package manager. There are 3 basic
varieties (lammps = no MPI, lammps-mpich = MPICH MPI library,
lammps-openmpi = OpenMPI MPI library) and for each support for
linking to the C library interface (lammps-devel, lammps-mpich-devel,
lammps-openmpi-devel), the header for compiling programs using
the C library interface (lammps-headers), and the LAMMPS python
module for Python 3. All packages can be installed at the same
time and the name of the LAMMPS executable is ``lmp`` and ``lmp_openmpi``
or ``lmp_mpich`` respectively. By default, ``lmp`` will refer to the
serial executable, unless one of the MPI environment modules is loaded
(``module load mpi/mpich-x86_64`` or ``module load mpi/openmpi-x86_64``).
Then the corresponding parallel LAMMPS executable can be used.

MESONT is a LAMMPS package for simulation of nanomechanics of nanotubes
(NTs). The model is based on a coarse-grained representation of NTs as
"flexible cylinders" consisting of a variable number of

interaction between the tubes are described by a mesoscopic force field
designed and parameterized based on the results of atomic-level
molecular dynamics simulations. The description of the force field is
provided in the papers listed below. This package contains two

This package contains two independent implementations of this model:
:doc:`pair_style mesont/tpm <pair_mesont_tpm>` is the original
implementation of the model based on a Fortran library in the
``lib/mesont`` folder. The second implementation is provided by the
mesocnt styles (:doc:`bond_style mesocnt <bond_mesocnt>`,
:doc:`angle_style mesocnt <angle_mesocnt>` and :doc:`pair_style mesocnt
<pair_mesocnt>`). The mesocnt implementation has the same features as
the original implementation with the addition of friction, but is
directly implemented in C++, interfaces more cleanly with general LAMMPS
functionality, and is typically faster. It also does not require its own
atom style and can be installed without any external libraries.

If you are not familiar with `Python <https://www.python.org>`_, it is a
powerful scripting and programming language which can do almost
everything that compiled languages like C, C++, or Fortran can do in

modules for many purposes (either bundled or easily installed from
Python code repositories). The major drawback is slower execution speed
of the script code compared to compiled programming languages. But when
