MedeA Software Training at CHPC National Conference 2023


Today, a deep comprehension of the interplay between chemical reactions and physical processes is achievable through rigorous atomistic-scale simulation techniques. The Materials Design's MedeA® simulation environment [1] efficiently supports material scientists and engineers globally by offering an integrated suite of user-friendly tools. These include the leading quantum chemical and molecular mechanics solver Vienna Ab-Initio Simulation Package (VASP) [2], the forcefield-based molecular dynamics and Monte Carlo engines #LAMMPS [3] and #GIBBS [4], and the quantum chemistry codes #Gaussian [5] and #MOPAC [6]. MedeA®'s property prediction modules efficiently use these engines to compute a wide range of material properties.

To reach across length and time scales up to the mesoscale and microscale, and to explore an expansive configuration space, MedeA offers versatile multi-scale methodologies. These encompass Universal Cluster Expansion, coarse-grain potentials, and automated machine-learned potential generation.
