\section{The DUFF Energy Functionals}
\label{sec:energyFunctionals}

The main energy functional set in OOPSE is DUFF (the Dipolar
Unified-atom Force Field). DUFF is a collection of parameters taken
from Seipman \emph{et al.}\cite{Siepmann1998} and Ichiye \emph{et
al.}\cite{liu96:new_model} The total energy of interaction is given by
Eq.~\ref{eq:totalPotential}:

\begin{multline}\label{eq:totalPotential}
V_{\text{lipid}} =
        \sum_{i}V_{i}^{\text{internal}}
        + \sum_i \sum_{j>i} \sum_{\alpha_i} 
        \sum_{\beta_j}V_{\text{LJ}}(r_{\alpha_{i}\beta_{j}}) \\
        +\sum_i\sum_{j>i}V_{\text{dp}}(r_{1_i,1_j},\Omega_{1_i},\Omega_{1_j})
\end{multline}
