ADF 2012 released

8 May 2014

SCM is proud to announce the 2012 release of its suite of chemical modeling programs: ADF, BAND, DFTB, MOPAC, ReaxFF, and COSMO-RS.

With the aid of our collaborators, we continue to broaden the scope and functionality of our software. Several enhancements and new features have been implemented in our well-established Density Functional Theory (DFT) codes for molecules (ADF) and periodic systems (BAND) and our more recent fluid thermodynamics COSMO-RS module. The 2012 release also features two new semi-empirical modules, Density Functional based Tight-Binding (DFTB), and Stewart’s MOPAC code. We now also offer ReaxFF for molecular dynamics studies of chemical reactions based on van Duin’s reactive force field methods.

New features in the ADF 2012 release:
