What is it?

Faunus is a C++/Python framework for molecular simulations. Focusing on Metropolis Monte Carlo techniques for studies of charged macro-molecules in aqueous solutions, we provide example programs for:

  • Protein-protein interactions in salt solutions (pmf, free energy surfaces, virial coefficients)
  • Proton fluctuations (pka predictions, charge regulation, ionization states)
  • Coarse Grained manybody simulations and phase equilibria.
  • Canonical, Grand Canonical, Isobaric-Isothermal statistical mechanical ensembles
  • General hamiltonian parallel tempering (temperature, screening length, bonds etc.)
  • Hofmeister and ion-specific effects
  • 4D simulations on a hypersphere

Is it free?

Yes - Faunus is released under the GNU Public Licence (GPL). Should you find it useful we would appreciate citation of the paper on the right side of this page.

I'm not a programmer - can I still use it?

Maybe - we provide many example programs, ready to use. Positive to new collaborations we can also help out creating tailored simulation programs.
