# Contributing to LAMMPS via GitHub
Thank your for considering to contribute to the LAMMPS software project.
Thank you for considering to contribute to the LAMMPS software project.
The following is a set of guidelines as well as explanations of policies and work flows for contributing to the LAMMPS molecular dynamics software project. These guidelines focus on submitting issues or pull requests on the LAMMPS GitHub project.
Thus please also have a look at:
* [The guide for submitting new features in the LAMMPS manual](https://www.lammps.org/doc/Modify_contribute.html)
* [The guide on programming style and requirement in the LAMMPS manual](https://www.lammps.org/doc/Modify_style.html)
* [The GitHub tutorial in the LAMMPS manual](http://lammps.sandia.gov/doc/Howto_github.html)
* [The guide for submitting new features in the LAMMPS manual](https://docs.lammps.org/Modify_contribute.html)
* [The guide on programming style and requirement in the LAMMPS manual](https://docs.lammps.org/Modify_requirements.html)

## I don't want to read this whole thing I just have a question!
> **Note:** Please do not file an issue to ask a general question about LAMMPS, its features, how to use specific commands, or how perform simulations or analysis in LAMMPS. Instead post your question to either the ['lammps-users' mailing list](https://lammps.sandia.gov/mail.html) or the [LAMMPS Material Science Discourse forum](https://matsci.org/lammps). You do not need to be subscribed to post to the list (but a mailing list subscription avoids having your post delayed until it is approved by a mailing list moderator). Most posts to the mailing list receive a response within less than 24 hours. Before posting to the mailing list, please read the [mailing list guidelines](https://lammps.sandia.gov/guidelines.html). Following those guidelines will help greatly to get a helpful response. Always mention which LAMMPS version you are using. The LAMMPS forum was recently created as part of a larger effort to build a materials science community and have discussions not just about using LAMMPS. Thus the forum may be also used for discussions that would be off-topic for the mailing list. Those will just have to be posted to a more general category.

Before posting to the forum, please read the general [guidelines](https://www.lammps.org/guidelines.html) and the forum specific [suggestions](https://matsci.org/t/please-read-this-first-guidelines-and-suggestions-for-posting-lammps-questions/49913).

The MatSci website may be also used for discussions that would be off-topic for the LAMMPS categories. Those will just have to be posted to a different category.
## How Can I Contribute?
There are several ways how you can actively contribute to the LAMMPS project: you can discuss compiling and using LAMMPS, and solving LAMMPS related problems with other LAMMPS users on the lammps-users mailing list or the forum, you can report bugs or suggest enhancements by creating issues on GitHub (or posting them to the lammps-users mailing list or posting in the LAMMPS Materials Science Discourse forum), and you can contribute by submitting pull requests on GitHub or e-mail your code
to one of the [LAMMPS core developers](https://lammps.sandia.gov/authors.html). As you may see from the aforementioned developer page, the LAMMPS software package includes the efforts of a very large number of contributors beyond the principal authors and maintainers.

### Discussing How To Use LAMMPS
The LAMMPS mailing list is hosted at SourceForge. The mailing list began in 2005, and now includes tens of thousands of messages in thousands of threads. LAMMPS developers try to respond to posted questions in a timely manner, but there are no guarantees. Please consider that people live in different timezone and may not have time to answer e-mails outside of their work hours.
You can post to list by sending your email to lammps-users at lists.sourceforge.net (no subscription required), but before posting, please read the [mailing list guidelines](https://lammps.sandia.gov/guidelines.html) to maximize your chances to receive a helpful response.

Anyone can browse/search previous questions/answers in the archives. You do not have to subscribe to the list to post questions, receive answers (to your questions), or browse/search the archives. You **do** need to subscribe to the list if you want emails for **all** the posts (as individual messages or in digest form), or to answer questions yourself. Feel free to sign up and help us out! Answering questions from fellow LAMMPS users is a great way to pay back the community for providing you a useful tool for free, and to pass on the advice you have received yourself to others. It improves your karma and helps you understand your own research better.

### Reporting Bugs
While developers writing code for LAMMPS are careful to test their code, LAMMPS is such a large and complex software, that it is impossible to test for all combinations of features under all normal and not so normal circumstances. Thus bugs do happen, and if you suspect, that you have encountered one, please try to document it and report it as an [Issue](https://github.com/lammps/lammps/issues) on the LAMMPS GitHub project web page. However, before reporting a bug, you need to check whether this is something that may have already been corrected. The [Latest Features and Bug Fixes in LAMMPS](https://lammps.sandia.gov/bug.html) web page lists all significant changes to LAMMPS over the years. It also tells you what the current latest development version of LAMMPS is, and you should test whether your issue still applies to that version.

When you click on the green "New Issue" button, you will be provided with a text field, where you can enter your message. That text field with contain a template with several headlines and some descriptions. Keep the headlines that are relevant to your reported potential bug and replace the descriptions with the information as suggested by the descriptions.
You can also attach small text files (please add the file name extension `.txt` or it will be rejected), images, or small compressed text files (using gzip, do not use RAR or 7-ZIP or similar tools that are uncommon outside of Windows machines). In many cases, bugs are best illustrated by providing a small input deck (do **not** attach your entire production input, but remove everything that is not required to reproduce the issue, and scale down your system size, that the resulting calculation runs fast and can be run on small desktop quickly).

### Pull Requests
Pull requests are the **only** way that changes get made to the LAMMPS distribution. So also the LAMMPS core developers will submit pull requests for their own changes and discuss them on GitHub. Thus if you submit a pull request it will be treated in a similar fashion. When you submit a pull request you may opt to submit a "Draft" pull request. That means your changes are visible and will be subject to testing, but reviewers will not be (auto-)assigned and comments will take into account that this is not complete. On the other hand, this is a perfect way to ask the LAMMPS developers for comments on non-obvious changes and get feedback and possible suggestions for improvements or recommendations about what to avoid.
Immediately after the submission, the LAMMPS continuing integration server at ci.lammps.org will download your submitted branch and perform a number of tests: it will tests whether it compiles cleanly under various conditions, it will also do a check on whether your included documentation translates cleanly and run some unit tests and other checks. Whether these tests are successful or fail will be recorded. If a test fails, please inspect the corresponding output on the CI server and take the necessary steps, if needed, so that the code can compile cleanly again. The test will be re-run each time the pull request is updated with a push to the remote branch on GitHub. If you are unsure about what you need to change, ask a question in the discussion area of the pull request.

The test will be re-run each time the pull request is updated with a push to the remote branch on GitHub. If you are unsure about what you need to change, ask a question in the discussion area of the pull request.
Next a LAMMPS core developer will self-assign and do an overall technical assessment of the submission. If you submitted a draft pull request, this will not happen unless you mark it "ready for review". If you are not yet invited as a LAMMPS collaborator, and your contribution seems significant, you may also receive an invitation for collaboration on the LAMMPS repository. As part of the assessment, the pull request will be categorized with labels. There are two special labels: `needs_work` (indicates that work from the submitter of the pull request is needed) and `work_in_progress` (indicates, that the assigned LAMMPS developer will make changes, if not done by the contributor who made the submit).
You may also receive comments and suggestions on the overall submission or specific details and on occasion specific requests for changes as part of the review. If permitted, also additional changes may be pushed into your pull request branch or a pull request may be filed in your LAMMPS fork on GitHub to include those changes.
The LAMMPS developer may then decide to assign the pull request to another developer (e.g. when that developer is more knowledgeable about the submitted feature or enhancement or has written the modified code). It may also happen, that additional developers are requested to provide a review and approve the changes. For submissions, that may change the general behavior of LAMMPS, or where a possibility of unwanted side effects exists, additional tests may be requested by the assigned developer.

LAMMPS and LAMMPS GUI universal binaries for macOS (arm64/x86_64)
=================================================================
This package provides universal binaries of LAMMPS and LAMMPS GUI that should
run on macOS systems running running macOS version 11 (Big Sur) or newer. Note
the binaries are compiled without MPI support and contain a compatible subset
of the available packages.
The following individual commands are included:
binary2txt lammps-gui lmp msi2lmp phana stl_bin2txt
After copying the LAMMPS_GUI folder into your Applications folder, please follow
these steps:
1. Open the Terminal app
2. Type the following command and press ENTER:
open ~/.zprofile
This will open a text editor for modifying the .zprofile file in your home
directory.
3. Add the following lines to the end of the file, save it, and close the editor
LAMMPS_INSTALL_DIR=/Applications/LAMMPS_GUI.app/Contents
LAMMPS_POTENTIALS=${LAMMPS_INSTALL_DIR}/share/lammps/potentials
LAMMPS_BENCH_DIR=${LAMMPS_INSTALL_DIR}/share/lammps/bench
MSI2LMP_LIBRARY=${LAMMPS_INSTALL_DIR}/share/lammps/frc_files
PATH=${LAMMPS_INSTALL_DIR}/bin:$PATH
export LAMMPS_POTENTIALS LAMMPS_BENCH_DIR PATH
4. In your existing terminal, type the following command make the settings active
source ~/.zprofile
Note, you don't have to type this in new terminals, since they will apply
the changes from .zprofile automatically.
Note: the above assumes you use the default shell (zsh) that comes with
MacOS. If you customized MacOS to use a different shell, you'll need to
modify that shell's init file (.cshrc, .bashrc, etc.) instead with
appropiate commands to modify the same environment variables.
5. Try running LAMMPS (which might fail, see step 7)
lmp -in ${LAMMPS_BENCH_DIR}/in.lj
6. Try running the LAMMPS GUI
lammps-gui ${LAMMPS_BENCH_DIR}/in.rhodo
Depending on the size and resolution of your screen, the fonts may be too
small to read. This can be adjusted by setting the environment variable
QT_FONT_DPI. The default value would be 72, so to increase the fonts by a
third, one can add to the .zprofile file the line
export QT_FONT_DPI=96
and reload as shown above.
7. Give permission to execute the commands (lmp, lammps-gui, msi2lmp, binary2txt, phana, stl_bin2txt)
MacOS will likely block the initial run of the executables, since they were
downloaded from the internet and are missing a known signature from an
identified developer. Go to "Settings" and search for "Security settings".
It should display a message that an executable like "lmp" was blocked. Press
"Open anyway", which might prompt you for your admin credentials. Afterwards
"lmp" and the other executables should work as expected.

Tests for styles of the same kind of style (e.g. pair styles or bond
styles) are performed with the same test executable using different

same kind it may be sufficient to add a suitable YAML file.
:doc:`Detailed instructions for adding tests <Developer_unittest>` are
provided in the Programmer Guide part of the manual.
Tests as shown by the ``ctest`` program are command lines defined in the
``CMakeLists.txt`` files in the ``unittest`` directory tree. A few
tests simply execute LAMMPS with specific command line flags and check
the output to the screen for expected content. A large number of unit
tests are special tests programs using the `GoogleTest framework
<https://github.com/google/googletest/>`_ and linked to the LAMMPS
library that test individual functions or create a LAMMPS class
instance, execute one or more commands and check data inside the LAMMPS
class hierarchy. There are also tests for the C-library, Fortran, and
Python module interfaces to LAMMPS. The Python tests use the Python
"unittest" module in a similar fashion than the others use `GoogleTest`.
These special test programs are structured to perform multiple
individual tests internally and each of those contains several checks
(aka assertions) for internal data being changed as expected.
Tests for force computing or modifying styles (e.g. styles for non-bonded
and bonded interactions and selected fixes) are run by using a more generic
test program that reads its input from files in YAML format. The YAML file
provides the information on how to customized the test program to test
a specific style and - if needed - with specific settings.
To add a test for another, similar style (e.g. a new pair style) it is

Accessing per-atom data
-----------------------
This page discusses how per-atom data is managed in LAMMPS, how it can
be accessed, what communication patters apply, and some of the utility
functions that exist for a variety of purposes.
Owned and ghost atoms
^^^^^^^^^^^^^^^^^^^^^
As described on the :doc:`parallel partitioning algorithms
<Developer_par_part>` page, LAMMPS uses a domain decomposition of the
simulation domain, either in a *brick* or *tiled* manner. Each MPI
process *owns* exactly one subdomain and the atoms within it. To compute
forces for tuples of atoms that are spread across sub-domain boundaries,
also a "halo" of *ghost* atoms are maintained within a the communication
cutoff distance of its subdomain.
The total number of atoms is stored in `Atom::natoms` (within any
typical class this can be referred to at `atom->natoms`. The number of
*owned* (or "local" atoms) are stored in `Atom::nlocal`; the number of
*ghost* atoms is stored in `Atom::nghost`. The sum of `Atom::nlocal`
over all MPI processes should be `Atom::natoms`. This is by default
regularly checked by the Thermo class, and if the sum does not match,
LAMMPS stops with a "lost atoms" error. For convenience also the
property `Atom::nmax` is available, this is the maximum of
`Atom::nlocal + Atom::nghost` across all MPI processes.
Per-atom properties are either managed by the atom style, or individual
classes. or as custom arrays by the individual classes. If only access
to *owned* atoms is needed, they are usually allocated to be of size
`Atom::nlocal`, otherwise of size `Atom::nmax`. Please note that not all
per-atom properties are available or updated on *ghost* atoms. For
example, per-atom velocities are only updated with :doc:`comm_modify vel
yes <comm_modify>`.
Atom indexing
^^^^^^^^^^^^^
When referring to individual atoms, they may be indexed by their local
*index*, their index in their `Atom::x` array. This is densely populated
containing first all *owned* atoms (index < `Atom::nlocal`) and then all
*ghost* atoms. The order of atoms in these arrays can change due to
atoms migrating between between subdomains, atoms being added or
deleted, or atoms being sorted for better cache efficiency. Atoms are
globally uniquely identified by their *atom ID*. There may be multiple
atoms with the same atom ID present, but only one of them may be an
*owned* atom.
To find the local *index* of an atom, when the *atom ID* is known, the
`Atom::map()` function may be used. It will return the local atom index
or -1. If the returned value is between 0 (inclusive) and `Atom::nlocal`
(exclusive) it is an *owned* or "local" atom; for larger values the atom
is present as a ghost atom; for a value of -1, the atom is not present
on the current subdomain at all.
If multiple atoms with the same tag exist in the same subdomain, they
can be found via the `Atom::sametag` array. It points to the next atom
index with the same tag or -1 if there are no more atoms with the same
tag. The list will be exhaustive when starting with an index of an
*owned* atom, since the atom IDs are unique, so there can only be one
such atom. Example code to count atoms with same atom ID in subdomain:
.. code-block:: c++
for (int i = 0; i < atom->nlocal; ++i) {
int count = 0;
while (sametag[i] >= 0) {
i = sametag[i];
++count;
}
printf("Atom ID: %ld is present %d times\n", atom->tag[i], count);
}
Atom class versus AtomVec classes
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The `Atom` class contains all kinds of flags and counters about atoms in
the system and that includes pointers to **all** per-atom properties
available for atoms. However, only a subset of these pointers are
non-NULL and which those are depends on the atom style. For each atom
style there is a corresponding `AtomVecXXX` class derived from the
`AtomVec` base class, where the XXX indicates the atom style. This
`AtomVecXXX` class will update the counters and per-atom pointers if
atoms are added or removed to the system or migrate between subdomains.

Another complexity of these tests stems from the need to capture
situations where LAMMPS will stop with an error, i.e. handle so-called
"death tests". Here the LAMMPS code will operate differently depending
on whether it was configured to throw C++ exceptions on errors or call
either ``exit()`` or ``MPI_Abort()``. In the latter case, the test code
also needs to detect whether LAMMPS was compiled with the OpenMPI
library, as OpenMPI is **only** compatible the death test options of the
GoogleTest library when C++ exceptions are enabled; otherwise those
"death tests" must be skipped to avoid reporting bogus failures. The
specifics of this step are implemented in the ``TEST_FAILURE()``
macro. These tests operate by capturing the screen output when executing
the failing command and then comparing that with a provided regular
expression string pattern. Example:

Troubleshooting failed unit tests
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The are by default no unit tests for newly added features (e.g. pair, fix,
or compute styles) unless your pull request also includes tests for the
added features. If you are modifying some features, you may see failures
for existing tests, if your modifications have some unexpected side effects
or your changes render the existing text invalid. If you are adding an
accelerated version of an existing style, then only tests for INTEL,
KOKKOS (with OpenMP only), OPENMP, and OPT will be run automatically.
Tests for the GPU package are time consuming and thus are only run
*after* a merge, or when a special label, ``gpu_unit_tests`` is added
to the pull request. After the test has started, it is often best to
remove the label since every PR activity will re-trigger the test (that
is a limitation of triggering a test with a label). Support for unit
tests with using KOKKOS with GPU acceleration is currently not supported.
When you see a failed build on GitHub, click on ``Details`` to be taken
to the corresponding LAMMPS Jenkins CI web page. Click on the "Exit"
symbol near the ``Logout`` button on the top right of that page to go to
the "classic view". In the classic view, there is a list of the
individual runs that make up this test run (they are shown but cannot be
inspected in the default view). You can click on any of those.
Clicking on ``Test Result`` will display the list of failed tests. Click
on the "Status" column to sort the tests based on their Failed or Passed
status. Then click on the failed test to expand its output.

The failed assertions provide line numbers in the test source
(e.g. ``test_main.cpp:56``), from which one can understand what
specific assertion failed.
Note that the force style engine runs one of a small number of systems
in a rather off-equilibrium configuration with a few atoms for a few
steps, writes data and restart files, uses :doc:`the clear command
<clear>` to reset LAMMPS, and then runs from those files with different
settings (e.g. newton on/off) and integrators (e.g. verlet vs. respa).
Beyond potential issues/bugs in the source code, the mismatch between
the expected and actual values could be that force arrays are not
properly cleared between multiple run commands or that class members are
not correctly initialized or written to or read from a data or restart
file.
While the epsilon (relative precision) for a single, `IEEE 754 compliant
<https://en.wikipedia.org/wiki/IEEE_754>`_, double precision floating
point operation is at about 2.2e-16, the achievable precision for the
tests is lower due to most numbers being sums over intermediate results
and the non-associativity of floating point math leading to larger
errors. In some cases specific properties of the tested style. As a
rule of thumb, the test epsilon can often be in the range 5.0e-14 to
1.0e-13. But for "noisy" force kernels, e.g. those a larger amount of
arithmetic operations involving `exp()`, `log()` or `sin()` functions,
and also due to the effect of compiler optimization or differences
between compilers or platforms, epsilon may need to be further relaxed,
sometimes epsilon can be relaxed to 1.0e-12. If interpolation or lookup
tables are used, epsilon may need to be set to 1.0e-10 or even higher.
For tests of accelerated styles, the per-test epsilon is multiplied
by empirical factors that take into account the differences in the order
of floating point operations or that some or most intermediate operations
may be done using approximations or with single precision floating point
math.
To rerun the failed unit test individually, change to the ``build`` directory
and run the test with verbose output. For example,
.. code-block:: bash
env TEST_ARGS=-v ctest -R ^MolPairStyle:lj_cut_coul_long -V
``ctest`` with the ``-V`` flag also shows the exact command line
of the test. One can then use ``gdb --args`` to further debug and
catch exceptions with the test command, for example,
.. code-block:: bash
gdb --args /path/to/lammps/build/test_pair_style /path/to/lammps/unittest/force-styles/tests/mol-pair-lj_cut_coul_long.yaml
It is recommended to configure the build with ``-D
BUILD_SHARED_LIBS=on`` and use a custom linker to shorten the build time
during recompilation. Installing `ccache` in your development
environment helps speed up recompilation by caching previous
compilations and detecting when the same compilation is being done
again. Please see :doc:`Build_development` for further details.

Use utils::count_words() functions instead of atom->count_words()
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. versionchanged:: 2Jun2020
The "count_words()" functions for parsing text have been moved from the
Atom class to the :doc:`utils namespace <Developer_utils>`. The
"count_words()" function in "utils" uses the Tokenizer class internally
to split a line into words and count them, thus it will not modify the
argument string as the function in the Atoms class did and thus had a
variant using a copy buffer. Unlike the old version, the new version
does not remove comments. For that you can use the
:cpp:func:`utils::trim_comment() function
<LAMMPS_NS::utils::trim_comment>` as shown in the example below.
Old:
.. code-block:: c++
nwords = atom->count_words(line);
int nwords = atom->count_words(buf);

Unknown identifier in data file
-------------------------------
This error happens when LAMMPS encounters a line of text in an unexpected format
while reading a data file. This is most commonly cause by inconsistent header and
section data. The header section informs LAMMPS how many entries or lines are expected in the
various sections (like Atoms, Masses, Pair Coeffs, *etc.*\ ) of the data file.
If there is a mismatch, LAMMPS will either keep reading beyond the end of a section
or stop reading before the section has ended.
This error happens when LAMMPS encounters a line of text with an
unexpected keyword while :doc:`reading a data file <read_data>`. This
would be either header keywords or section header keywords. This is
most commonly due to a mistyped keyword or due to a keyword that is
inconsistent with the :doc:`atom style <atom_style>` used.
Such a mismatch can happen unexpectedly when the first line of the data
is *not* a comment as required by the format. That would result in
LAMMPS expecting, for instance, 0 atoms because the "atoms" header line
is treated as a comment.
The header section informs LAMMPS how many entries or lines are expected
in the various sections (like Atoms, Masses, Pair Coeffs, *etc.*\ ) of
the data file. If there is a mismatch, LAMMPS will either keep reading
beyond the end of a section or stop reading before the section has
ended. In that case the next line will not contain a recognized keyword.
Such a mismatch can also happen when the first line of the data
is *not* a comment as required by the format, but a line with a valid
header keyword. That would result in LAMMPS expecting, for instance,
0 atoms because the "atoms" header line is the first line and thus
treated as a comment.
Another possibility to trigger this error is to have a keyword in the
data file that corresponds to a fix (e.g. :doc:`fix cmap <fix_cmap>`)
but the :doc:`read_data <read_data>` command is missing the (optional)
arguments that identify the fix and the header keyword and section
keyword or those arguments are inconsistent with the keywords in the
data file.
.. _err0002:
Incorrect format in ... section of data file
--------------------------------------------
This error happens when LAMMPS reads the contents of a section of a
:doc:`data file <read_data>` and the number of parameters in the line
differs from what is expected. This most commonly happens, when the
atom style is different from what is expected for a specific data file
since changing the atom style usually changes the format of the line.
This error can also happen when the number of entries indicated in the
header of a data file (e.g. the number of atoms) is larger than the
number of lines provided (e.g. in the corresponding Atoms section)
and then LAMMPS will continue reading into the next section and that
would have a completely different format.
