  • Coulomb Potential
  • Long-Range Coulomb Potential

Closures

  • Hyper-Netted Chain (HNC)
  • Percus-Yevick (PY)
  • Kovalenko-Hirata (KH)
  • Partial Series Expansion (PSE-n)

Usage

Pass the input file as an argument to rism_ctrl.py

python rism_ctrl.py INPUT.toml

Example input files are provided in pyrism\data with references in pyrism\data\README.md

Future Work
