Ellipoidal Model

gyration.gif (9932 Byte) To develop a coarse-grained model monomer  we proceed in steps. As input we use the results of ab-initio calculations of the geometry and the torsional potentials. Furthermore we use monomer length and monomer angle distributions that have been determined via Monte-Carlo simulations from the ab-initio results.

The distributions are temperature dependent and the fitting must be carried out for each simulation temperature independently.
  • compute a  potential around one resp. two atomistic monomer units.

  • from the distributions above determine the bonded coarse-grained interactions.

  • determine the non-bonded coarse-grained interaction constants.
