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
# 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
Finally, in our VM image LAMMPS was compiled and installed into
$HOME/.local using the following CMake steps:
cmake -C ../cmake/presets/most.cmake -D PKG_KIM=on -D BUILD_SHARED_LIBS=on -D LAMMPS_EXCEPTIONS=on ../cmake
make -j 4
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.
