FHI98md is an efficient code to perform density functional theory total-energy calculations for materials ranging from insulators to transition metals. The package employs first-principles pseudopotentials, and a plane-wave basis-set. For exchange and correlation both the local density and generalized gradient approximations are implemented. The code has a low storage demand and performs efficiently on low budget personal computers as well as high performance computers.

Features:

Fast initialization by atomic orbitals
Atomic relaxation
Molecular dynamics at finite temperatures
Charge states
Dipole correction
Electric fields
Different schemes to find electronic ground state:
Steepest Descent
Damped Joannopoulos alghorithm
Williams-Soler alghorithm

LDA, GGA and PBE XC functionals
Various output routines : (charge density, electrostatic & effective potentials, 3D- and XY-averaged)
Automatic input generation:
symmetry searches
k-point generation
predefined atomic structures

Only executable necessary
Highly optimized code:
Low memory requirements
Use of optimized libraries

Dynamic memory allocation
Utility programs :
