ABSTRACT

The simulation of large biomolecules and biological assemblies requires to achieve an optimal balance between physical realism and computational efficiency. We describe how an effective strategy is based on a dual representation, whereby macromolecules are described by means of a coarse grained, particle-based representation, while aqueous solvent and electrolytes are represented by a mesoscopic, kinetic treatment. The joint usage of the Molecular Dynamics and Lattice Boltzmann techniques provides an optimal combination for these representations and allows simulating from proteins to polynucleotides under a wide range of equilibrium and off-equilibrium conditions.
