Results from an EMSL Arrows Calculation
| EMSL Arrows is a revolutionary approach to materials and chemical simulations that uses NWChem and chemical computational databases to make materials and chemical modeling accessible via a broad spectrum of digital communications including posts to web APIs, social networks, and traditional email. |
Molecular modeling software has previously been extremely complex, making it prohibative to all but experts in the field, yet even experts can struggle to perform calculations. This service is designed to be used by experts and non-experts alike. Experts can carry out and keep track of large numbers of complex calculations with diverse levels of theories present in their workflows. Additionally, due to a streamlined and easy-to-use input, non-experts can carry out a wide variety of molecular modeling calculations previously not accessible to them.
