COarse-Grained molecular dynamics program by NAgoya Cooperation
COGNAC is a general molecular dynamics simulation program which covers a large class of molecular models, ranging from full atomistic models to bead-spring models. Many potential functions used in coarse-grained models are implemented in COGNAC, such as Lennard-Jones, Gay-Berne and Coulombic potentials, and new potential functions can be added easily. COGNAC can conduct MD simulations under various conditions such as under constant temperature, under deformation (elongation and shear), and under external fields. COGNAC has a special function, called zooming, which generates the equilibrium molecular configuration for given density profile of atoms.
