FOMD - Floating Orbital Molecular Dynamics

Welcome to the website of ForPleasure - a program for floating orbital molecular dynamics (FOMD) simulations.

FOMD indicates that ab initio molecular dynamics simulations are performed at the Hartree-Fock level of theory. The basis functions are, however, not atom-centered. Instead, the coordinates of the center of the Gaussian Type functions are optimized at each step of the MD trajectory. Currently, the following features are implemented in ForPleasure:

• SCF energy and gradient evaluation
• FO scheme applying a quasi-Newton optimization routine
• velocity-Verlet integration algorithm
• electron and spin density output
• evaluation of dipole moments
