SMG Features of Ellipsoids•Complete flexibility of Charge and Dipole Distributions
•Complete flexibility of Connectivity to other Ellipsoids
•Complete flexibility of oreintation (for Monte Carlo and Brownian Dynamics Trajectories)
•Polarizability Tensor
•Computes all electrostatics with other Ellipsoids and arbitrary External Field
•A contact function to find Ellipsoid-Ellipsoid interactions
•Can have either Hard-Shell Repulsion or Leonard-Jones Interactions
•Solvent free energies and exposure factors (use the rolling ball method)
•Can generate dendrimers, polymers and lattices of ellipsoids

By choosing a tilt
angle for the three chromophores (~60°) the experimental enhancement (of ~ 2 fold) was realized.
