Beginners Tutorial - Manual Installation Steps
If you fail to use the virtual machine, there is still the option to manually download the materials and preparing your Linux/Unix/MacOS system.
Here is a minimal set of steps needed to create an environment similar to the VirtualBox image. Note that you will still have to install OVITO and other dependencies (compilers, cmake, etc.) manually.
# download tutorial material into home directory cd $HOME wget https://download.lammps.org/workshops/Aug21/tutorial/beginners_tutorial.tar.gz wget https://github.com/lammps/lammps/archive/refs/tags/patch_30Jul2021.tar.gz # extract downloaded content into $HOME tar xvzf beginners_tutorial.tar.gz tar xvzf patch_30Jul2021.tar.gz # rename extracted source code folder to $HOME/lammps mv lammps-patch_30Jul2021 lammps # modify environment # to make permanent put this at the end of $HOME/.bash_profile or $HOME/.bashrc # (recommended) export PATH=$HOME/tools/tutorial:$HOME/.local/bin:$PATH export LD_LIBRARY_PATH=$HOME/.local/lib64:$LD_LIBRARY_PATH
Finally, in our VM image LAMMPS was compiled and installed into
$HOME/.local using the following CMake steps:
cd $HOME/lammps mkdir build cd build cmake -C ../cmake/presets/most.cmake -D PKG_KIM=on -D BUILD_SHARED_LIBS=on -D LAMMPS_EXCEPTIONS=on ../cmake make -j 4 make install
On Windows, there is also the possibility to install precompiled Windows binaries. Both LAMMPS and Ovito have installer packages. To improve the command-line on Windows 10, try the Windows Terminal app.
