  $DMol^3$ is a commercial (and academic) software package which uses density functional theory with a numerical radial function basis set to calculate the electronic properties of molecules, clusters, surfaces and crystalline solid materials
  
  from first principles. $DMol^3$ can either use gas phase boundary conditions or 3D periodic boundary conditions for solids or simulations of lower-dimensional periodicity. It has also pioneered the use of the conductor-like screening model COSMO Solvation Model for quantum simulations of solvated molecules and recently of wetted surfaces. $DMol^3$ permits geometry optimisation and saddle point search with and without geometry constraints, as well as calculation of a variety of derived properties of the electronic configuration. $DMol^3$ development started in the early eighties with B. Delley then associated with A.J. Freeman and D.E. Ellis at Northwestern University. In 1989 $DMol^3$ appeared as DMol, the first commercial density functional package for industrial use by Biosym Technologies now Accelrys. Delley's 1990 publication was cited more than 3000 times.
