2D and 3D wormlike chain generator for Python and written in C++.

PolymerCpp is a small program for generating three-dimensional wormlike chains (WLC), a common and relatively simple model in polymer physics. A WLC describes a semi-flexible polymer, i.e. one that is rigid over short length scales and flexible over long ones. The characteristic length scale that separates these two regimes is known as the persistence length.

PolymerCpp provides a number of Python functions that exposes the C++ routines for generating 3D WLCs, including

1. infinitesimally thin WLCs
2. self-avoiding WLCs

PolymerCpp was written by Marcel Stefko and Kyle M. Douglass in the Laboratory of Experimental Biophysics for modeling DNA.

Important Note: The self-avoiding wormlike chain in this program does not produce the predicted scaling behavior for the moments (radius of gyration and end-to-end distance). Do not use the self-avoiding chain if you require exact agreement with the Flory theory.
