DPDcoeffs

1. Generate dissipative particle dynamics interaction coefficients.

  • generate reasonable clusters of 6 water molecules
  • add random noise to coordinates using wiggle_water.py
  • parse coordinates from g09 outfiles of relaxed clusters
  • create pairs of clusters and perform SP calculations on them at various distances ranging from 4 AA (almost overlap) to ca 8 AA (too far)
  • parse the energy curves of each pair

2. Set and perform DPD simulations in LAMMPS

Simulate DPD binary mixture or diblock copolymer melt, as researched in Groot and Madden, JCP, 1998.

Scripts:

  • gen_diblock_copolymer.py
  • gen_binmixt.py
  • gen_random_poly.py
  • order_param.py

Dependencies

  • Python3: sudo pip3 install numpy docopt

Compile f_rdf.f90 using f2py3 -c f_rdf.f90 -m f_rdf
