cdftpy 0.1.0

Classical density functional theory code

CDFTPY: Python package for performing classical density functional theory calculations for molecular liquids

Marat Valiev and Gennady Chuev

Quick Start:

---

Standard RISM calculation can be run as

rism1d <input_file>

RSDFT calculation can be run as

rsdft1d <input_file>

where <input_file> is the optional input file. An example of the latter for simulation of ion solvation in two-site water model is given below

 <solute>
 # site   sigma        eps(kj/mol)    charge(e)    x   y   z
 Cl       4.83         0.05349244     -1.0         0.0 0.0 0.0
 <simulation>
 solvent s2
 tol 1.0E-7
 max_iter 200
 
 #optional analysis
 <analysis>
 rdf_peaks
 <output>
 rdf

In the absense of the input file, the calculation will be run interactively
