Synopsis

csg_orientcorr [Options]

csg_orientcorr [--help]

Description

Calculates the orientational correlation function <3/2*u(0)*u(r) - 1/2> for a polymer melt, where u is the vector pointing along a bond and  r the distance between bond segments (centered on middle of bond).

The output is correlation.dat (with intra-molecular contributions) and correlation_excl.dat, where inter-molecular contributions are excluded.
