Molcas is an ab initio quantum chemistry software package developed by scientists to be used by scientists. The basic philosophy is is to be able to treat general electronic structures for molecules consisting of atoms from most of the periodic table. As such, the primary focus of the package is on multiconfigurational methods with applications typically connected to the treatment of highly degenerate states.
Key aspects of Molcas:
- SCF/DFT, CASSCF/RASSCF, CASPT2/RASPT2
- Fast, accurate, and robust code
Online information from vendor:¶
License and access policy:¶
Molcas comes with a non-free computer center license, though it is free for academic employees from the Nordic region. The HPC group @ UiT have an agreement with Molcas as a part of the old application management project, that we do make a central install of the code - but users who wants access needs to document that they have made an agreement with Molcas. This proof of agreement should then be mailed (e or non-e) to email@example.com to be granted membership of the molcas group on Stallo.
For the future, we are considering establishing the same policy as for ORCA, especially since the vendor has done a substantial job at decomplicating the install procedure using CMake.
