Classical forcefield-based simulations complement electronic structure methods. Accurately parameterized forcefield-based classical methods extend the scope and range of electronic structure methods to substantially larger length and time scales. While forcefield-based simulations can provide unique insights and property data, classical forcefields have been difficult to use and to develop. However, the latest developments of the MedeA software environment provides state-of-the-art forcefield support along with powerful tools to develop and deploy forcefields in simulating sophisticated systems and solving complex problems. This webinar will provide a review on forcefields supported in the MedeA environment and an update on the latest developments in MedeA for forcefield development.
