General Utility Lattice Program

This is a program for the simulation of solids, molecules and defects using interatomic potential models. Originally designed for the modelling of ionic materials and incorporating the shell model for ionic polarization, GULP now contains all the functionality required to treat more general systems such as biological molecules and metals. The program is available to academics at no charge for non-commercial research, contact Other users contact Molecular Simulations Inc. More information at
