MedeA 3.9 - Materials Acceleration  

Dr. Gerhard Engel, Senior Director of Strategy and Innovation at Materials Design, comments: 

MedeA VASP is the gold standard for quantum atomistic simulations of materials, trusted by an unequaled and ever-growing number of researchers across academia, government, and industry worldwide. MedeA 3.9 provides access to the latest VASP 6.4.3 release and is designed to harness the computational power of modern AI chips in a way that maximizes user productivity. With the addition of new VASP PAW potentials, we are enabling new heights of accuracy and efficiency in materials simulations. Building on this foundation, the MedeA 3.9 materials modeling environment empowers researchers to explore ever-larger time- and length scales through the seamless integration of machine-learned potentials, advanced mesoscale simulation tools, and a unique and augmented microstructure builder with first principles and atomistic computational engines. Moreover, important enhancements to our flagship PCFF+ potential make the MedeA user environment even more powerful for battery development.”

Dr. Engel reflects: "Advancements in algorithms and hardware have come a long way since I first started working with atomistic simulations software at Cambridge University decades ago. They have propelled us toward the realization of truly predictive materials simulations. MedeA embodies the synergy between physics, computer science, and artificial intelligence, facilitating high-throughput scientific computations and seamless sharing of data and workflows through its intuitive user interface, through the MedeA JobServer, and through the flexible MedeA Flowchart workflow environment.  


Dr. Erich Wimmer, Chief Scientific Officer and Chairman of the Board at Materials Design, adds: "Over the years, we have seen waves of innovation in computational materials science. At present, we are witnessing a confluence of innovation; progress in fundamental theory, machine learning, and access to unprecedented compute resources amplify the impact and importance of computational materials modeling. The MedeA materials modeling environment leverages all of these developments by connecting the atomistic and macroscopic worlds like never before. My colleagues and I at Materials Design are proud of MedeA 3.9 and we are looking forward to seeing its ongoing impact in materials research across the world."
