Building structures for Lammps

  1. Install EMC by downloading the file and copying it into the lammps directory

    http://montecarlo.sourceforge.net/emc/Download.html

  2. Unpack the archive by using:

    tar -xzvf <name of the file .tgz>

  3. Go into the <emc directory>

  4. Add two directories to the path:

    export PATH="/Users/bazilevs/packages/lammps/emcv9.4.3/bin:$PATH"
    export PATH="/Users/bazilevs/packages/lammps/emcv9.4.3/scripts:$PATH"
    # format of the
    export PATH="<your path to the main emc directory>/scripts:$PATH"
    
    1. Go into the examples cd ./examples/setup/chemistry/polymer/random
  5. Lets try to run the sample file:

    # build the emc input file
    ./polymer.esh
    # build the lammps and vmd files
    emc_macos build.emc
    
  6. After that you get the following:
