-> **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.

 ### 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.

 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.

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 Release Steps
+
+The following notes chronicle the current steps for preparing and
+publishing LAMMPS releases.  For definitions of LAMMPS versions and
+releases, please refer to [the corresponding section in the LAMMPS
+manual](https://docs.lammps.org/Manual_version.html).
+
+## LAMMPS Feature Release
+
+A LAMMPS feature release is currently prepared after about 500 to 750
+commits to the 'develop' branch or after a period of four weeks up to
+two months.  This is not a fixed rule, though, since external
+circumstances can cause delays in preparing a release, or pull requests
+that are desired to be merged for the release are not yet completed.
+
+### Preparing a 'next\_release' branch
+
+Create a 'next\_release' branch off 'develop' and make the following changes:
+
+- set the LAMMPS\_VERSION define to the planned release date in
+  src/version.h in the format "D Mmm YYYY" or "DD Mmm YYYY"
+- remove the LAMMPS\_UPDATE define in src/version.h
+- update the release date in doc/lammps.1
+- update all TBD arguments for ..versionadded::, ..versionchanged::
+  ..deprecated:: to the planned release date in the format "DMmmYYYY" or
+  "DDMmmYYYY"
+- check release notes for merged new features and check if
+  ..versionadded:: or ..versionchanged:: are missing and need to be
+  added
+
+Submit this pull request.  This is the last pull request merged for the
+release and should not contain any other changes. (Exceptions: this
+document, last minute trivial(!) changes).
+
+This PR shall not be merged before **all** pending tests have completed
+and cleared.  We currently use a mix of automated tests running on
+either Temple's Jenkins cluster or GitHub workflows.  Those include time
+consuming tests not run on pull requests.  If needed, a bug-fix pull
+request should be created and merged to clear all tests.
+
+### Create release on GitHub
+
+When all pending pull requests for the release are merged and have
+cleared testing, the 'next\_release' branch is merged into 'develop'.
+
+Check out or update the 'develop' branch locally, pull the latest
+changes, merge them into 'release' with a fast forward(!) merge, and
+apply a suitable release tag (for historical reasons the tag starts with
+"patch_" followed by the date, and finally push everything back to
+GitHub.  There should be no commits made to 'release' but only
+fast forward merges.  Example:
+
+```
+git checkout develop
+git pull
+git checkout release
+git pull
+git merge --ff-only develop
+git tag -s -m "LAMMPS feature release 4 February 2025" patch_4Feb2025
+git push git@github.com:lammps/lammps.git --tags develop release
+```
+
+Applying this tag will trigger two actions on the Temple Jenkins cluster:
+- The online manual at https://docs.lammps.org/ will be updated to the
+  state of the 'release' branch.  Merges to the 'develop' branch will
+  trigger updating https://docs.lammps.org/latest/ so by reviewing the
+  version of the manual under the "latest" URL, it is possible to preview
+  what the updated release documentation will look like.
+- A downloadable tar archive of the LAMMPS distribution that includes the
+  html format documentation and a PDF of the manual will be created and
+  uploaded to the download server at https://download.lammps.org/tars
+  Note that the file is added, but the `index.html` file is not updated,
+  so it is not yet publicly visible.
+
+Go to https://github.com/lammps/lammps/releases and create a new (draft)
+release page with a summary of all the changes included and references
+to the pull requests they were merged from or check the existing draft
+for any necessary changes from pull requests that were merged but are
+not listed.  Then select the applied tag for the release in the "Choose
+a tag" drop-down list. Go to the bottom of the list and select the "Set
+as pre-release" checkbox.  The "Set as the latest release" button is
+reserved for stable releases and updates to them.
+
+If everything is in order, you can click on the "Publish release"
+button.  Otherwise, click on "Save draft" and finish pending tasks until
+you can return to edit the release page and publish it.
+
+### Prepare pre-compiled packages, update packages to GitHub
+
+A suitable build environment is provided with the
+https://download.lammps.org/static/fedora41_musl_mingw.sif container
+image.  The corresponding container build definition file is maintained
+in the tools/singularity folder of the LAMMPS source distribution.
+
+#### Fully portable static Linux x86_64 non-MPI binaries
+
+The following commands use the Fedora container to build a fully static
+LAMMPS installation using a musl-libc cross-compiler, install it into a
+`lammps-static` folder, and create a tarball called
+`lammps-linux-x86_64-4Feb2025.tar.gz` (or using a corresponding date
+with a future release) from the `lammps-static` folder.
+
+``` sh
+rm -rf release-packages
+mkdir release-packages
+cd release-packages
+wget https://download.lammps.org/static/fedora41_musl_mingw.sif
+apptainer shell fedora41_musl_mingw.sif
+git clone -b release --depth 10 https://github.com/lammps/lammps.git lammps-release

+tar -czvvf ../lammps-linux-x86_64-4Feb2025.tar.gz lammps-static
+exit # fedora 41 container
+cd ..
+```
+
+The resulting tar archive can be uploaded to the GitHub release page with:
+
+``` sh

+
+Make sure you have the `flatpak` and `flatpak-builder` packages
+installed locally (they require binaries that run with elevated
+privileges and thus cannot be used from the container) and build a
+LAMMPS and LAMMPS-GUI flatpak bundle in the `release-packages` folder
+with:
+
+``` sh
+cd release-packages
+flatpak --user remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
+flatpak-builder  --force-clean --verbose --repo=$PWD/flatpak-repo --install-deps-from=flathub --state-dir=$PWD --user --ccache --default-branch=release flatpak-build lammps-release/tools/lammps-gui/org.lammps.lammps-gui.yml
+flatpak build-bundle --runtime-repo=https://flathub.org/repo/flathub.flatpakrepo --verbose $PWD/flatpak-repo ../LAMMPS-Linux-x86_64-GUI-4Feb2025.flatpak org.lammps.lammps-gui release
+cd ..
+```
+
+The resulting flatpak bundle file can be uploaded to the GitHub release page with:
+
+``` sh
+gh release upload patch_4Feb2025 LAMMPS-Linux-x86_64-GUI-4Feb2025.flatpak
+```
+
+#### LAMMPS Source tarball
+
+The container for the static binary can also be used to prepare the source
+tarball including the HTML and PDF manual (this is currently done automatically
+when the releases is created and the tarball uploaded to https://download.lammps.org/tars/).
+The steps are as follows:
+
+``` sh
+cd release-packages
+apptainer shell fedora41_musl_mingw.sif
+cd lammps-release
+rm -f ../release.tar*
+git archive --output=../release.tar --prefix=lammps-4Feb2025/ HEAD
+cd doc
+make clean-all
+make html pdf
+tar -rf ../../release.tar --transform 's,^,lammps-4Feb2025/doc/,' html Manual.pdf
+gzip -9v ../../release.tar
+mv ../../release.tar.gz ../../lammps-src-4Feb2025.tar.gz
+exit # fedora41 container
+cd ..
+```
+
+The resulting source tarball can be uploaded to the GitHub release page with:
+
+``` sh
+gh release upload patch_4Feb2025 lammps-src-4Feb2025.tar.gz
+```
+
+#### Build Windows Installer Packages with MinGW Linux-to-Windows Cross-compiler
+
+The various Windows installer packages can also be built with
+apptainer container image.
+
+``` sh
+cd release-packages
+apptainer shell fedora41_musl_mingw.sif
+git clone --depth 10 https://github.com/lammps/lammps-packages.git lammps-packages
+cd lammps-packages/mingw-cross
+ln -sf ../../lammps-release lammps
+./buildall.sh release >& mk.log & less +F mk.log
+```
+
+The installer with the GUI included can be uploaded to the GitHub release page with:
+
+``` sh
+ln -sf LAMMPS-64bit-GUI-4Feb2025.exe LAMMPS-Win10-64bit-GUI-4Feb2025.exe
+gh release upload patch_4Feb2025 LAMMPS-Win10-64bit-GUI-4Feb2025.exe
+```
+
+The symbolic link is used to have a consistent naming scheme for the packages
+attached to the GitHub release page.
+
+#### Clean up:
+
+``` sh
+cd ..
+rm -r release-packages
+```
+
+#### Build Multi-arch App-bundle with GUI for macOS
+
+Building app-bundles for macOS is not as easily automated and portable
+as some of the other steps.  It requires a machine actually running
+macOS.  In that machine the Xcode compiler package needs to be
+installed. This also includes tools for building and manipulating disk
+images.  This compiler supports building executables for both, the
+x86_64 and the arm64 architectures.  This requires building with CMake
+and using the CMake settings:
+
+``` sh
+-D CMAKE_OSX_ARCHITECTURES=arm64;x86_64
+-D CMAKE_OSX_DEPLOYMENT_TARGET=11.0
+```
+
+This will add the compiler flags `-arch arm64 -arch x86_64
+-mmacosx-version-min=11.0` and thus produce object for both
+architectures and support for macOS versions back to version 11 (aka Big
+Sur).  With these settings the following libraries should be compiled
+and installed (e.g. to `$HOME/.local`) as static libraries only:
+- libomp taken from the LLVM/Clang source distribution (to support OpenMP)
+- jpeg
+- zlib
+- png
+- Qt (for LAMMPS-GUI)
+
+When configuring LAMMPS the `cmake/presets/clang.cmake` should be used
+and as many packages as possible enabled. For LAMMPS-GUI, MPI should be
+disabled with `-D BUILD_MPI=OFF` and LAMMPS-GUI enabled with 
+`-D BUILD_LAMMPS_GUI=ON`.  If the CMake configuration is successful,
+settings for building a macOS app-bundle are enabled and with `cmake
+--build build --target dmg` extra steps will be executed that will build
+a macOS application installer image under the name
+`LAMMPS_GUI-macOS-multiarch-4Feb2025.dmg`
+
+The application image can be uploaded to the GitHub release page with:
+
+``` sh
+ln -sf LAMMPS_GUI-macOS-multiarch-4Feb2025.dmg LAMMPS-macOS-multiarch-GUI-4Feb2025.dmg
+gh release upload patch_4Feb2025 LAMMPS-macOS-multiarch-GUI-4Feb2025.dmg
+```
+
+The symbolic link is used to have a consistent naming scheme for the packages
+attached to the GitHub release page.
+
+We are currently building the application images on macOS 12 (aka Monterey).
+
+#### Build Linux x86_64 binary tarball with GUI on Ubuntu 20.04LTS
+
+While the flatpak Linux version uses portable runtime libraries provided
+by the flatpak environment, we also build regular Linux executables that
+use a wrapper script and matching shared libraries in a tarball.  To be
+compatible with many Linux distributions, one has to build this on a
+very old Linux distribution, since most Linux system libraries are
+usually backward compatible but not forward compatible.  This is
+currently done on an Ubuntu 20.04LTS system. Once LAMMPS moves to
+require CMake 3.20 and C++17, we will have to move to Ubuntu 22.04LTS.
+This installation (either on a real or a virtual machine) should have
+the packages installed that are indicated in
+`tools/singularity/ubuntu20.04.def` plus Qt version 5.x with development
+headers, so that LAMMPS-GUI can be compiled.
+
+Also the building of the binary tarball and setup of the bundled
+libraries and wrapper scripts is automated and can executed with `cmake
+--build build --target tgz`.  This should produce a file
+`LAMMPS_GUI-Linux-amd64-4Feb2025.tar.gz` which can be uploaded to the
+GitHub release page with:
+
+``` sh
+ln -sf LAMMPS_GUI-Linux-amd64-4Feb2025.tar.gz LAMMPS-Linux-x86_64-GUI-4Feb2025.tar.gz
+gh release upload patch_4Feb2025 LAMMPS-Linux-x86_64-GUI-4Feb2025.tar.gz
+```
+
+### Update download page on LAMMPS website
+
+Check out the LAMMPS website repo
+https://github.com/lammps/lammps-website.git and edit the file
+`src/download.txt` for the new release.  Test translation with `make
+html` and review `html/download.html` Then add and commit to git and
+push the changes to GitHub.  The Temple Jenkis cluster will
+automatically update https://www.lammps.org/download.html accordingly.
+
+Also notify Steve of the release so he can update `src/bug.txt` on the
+website from the available release notes.
+
+## LAMMPS Stable Release
+
+A LAMMPS stable release is prepared about once per year in the months
+July, August, or September.  One (or two, if needed) feature releases
+before the stable release shall contain only bug fixes or minor feature
+updates in optional packages.  Also substantial changes to the core of
+the code shall be applied rather toward the beginning of a development
+cycle between two stable releases than toward the end.  The intention is
+to stablilize significant change to the core and have outside users and
+developers try them out during the development cycle; the sooner the
+changes are included, the better chances for spotting peripheral bugs
+and issues.
+
+### Prerequesites
+
+Before making a stable release all remaining backported bugfixes shall
+be released as a (final) stable update release (see below).
+
+A LAMMPS stable release process starts like a feature release (see
+above), only that this feature release is called a "Stable Release
+Candidate" and no assets are uploaded to GitHub.
+
+### Synchronize 'maintenance' branch with 'release'
+
+The state of the 'release' branch is then transferred to the
+'maintenance' branch (which will have diverged significantly from
+'release' due to the selectively backported bug fixes).
+
+### Fast-forward merge of 'maintenance' into 'stable' and apply tag
+
+At this point it should be possible to do a fast-forward merge of
+'maintenance' to 'stable' and then apply the stable\_DMmmYYYY tag.
+
+### Push branches and tags
+
+## LAMMPS Stable Update Release
+
+After making a stable release, bugfixes from the 'develop' branch
+are selectively backported to the 'maintenance' branch.  This is
+done with "git cherry-pick \<commit hash\>' wherever possible.
+The LAMMPS\_UPDATE define in "src/version.h" is set to "Maintenance".
+
+### Prerequesites
+
+When a sufficient number of bugfixes has accumulated or an urgent
+or important bugfix needs to be distributed a new stable update
+release is made.  To make this publicly visible a pull request
+is submitted that will merge 'maintenance' into 'stable'.  Before
+merging, set LAMMPS\_UPDATE in "src/version.h" to "Update #" with
+"#" indicating the update count (1, 2, and so on).
+Also draft suitable release notes under https://github.com/lammps/lammps/releases
+
+### Fast-forward merge of 'maintenance' into 'stable', apply tag, and publish
+
+Do a fast-forward merge of 'maintenance' to 'stable' and then
+apply the stable\_DMmmYYYY\_update# tag and push branch and tag
+to GitHub. The corresponding pull request will be automatically
+closed.   Example:
+
+```
+git checkout maintenance
+git pull
+git checkout stable
+git pull
+git merge --ff-only maintenance
+git tag -s -m 'Update 2 for Stable LAMMPS version 29 August 2024' stable_29Aug2024_update2
+git push git@github.com:lammps/lammps.git --tags maintenance stable
+```
+
+Associate draft release notes with new tag and publish as "latest release".
+
+On https://ci.lammps.org/ go to "dev", "stable" and manually execute
+the "update\_release" task. This will update https://docs.lammps.org/stable
+and prepare a stable tarball.
+
+### Build and upload binary packages and source tarball to GitHub
+
+The build procedure is the same as for the feature releases, only
+that packages are built from the 'stable' branch.

 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 is fast-forwarded to that tag.  This is often referred
-to as a patch release. Bug fixes and updates are
-applied first to the `develop` branch.  Later, they appear in the `release`
-branch when the next patch release occurs.

+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.
