New Software Release: MedeA 3.0 -- Getting to Science Faster

Light souces

The Materials Design MedeA® Environment provides the highest quality materials science simulation capabilities available today, based on an innovative architecture, careful software engineering, and thorough validation. MedeA® 3.0 is a substantial new release of the MedeA Environment.

MedeA 3.0 features:

  • A complete user interface (UI) refresh with updated icons, improved user experience with responsive dialogs, and enhanced operating system compliance on both Windows and Linux improving usability and enabling users to conduct cutting edge research with maximal efficiency,

  • Builder capability extensions - facilitating the creation of complex crystalline and amorphous systems,

  • A new module (MedeA HT-Descriptors) - providing easy access to numerous topological and geometrical descriptors, in High-throughput mode,

  • Updates to the MedeA Forcefield library with new forcefield types and parameter sets and extensions broadening coverage and improving simulation accuracy,

  • Use of reactive forcefields to simulate deposition and etching processes,

  • Calculation and Analysis extensions for MedeA's Optical Spectra - providing the ability to predict colors of metals

MedeA is the leading professional software environment for atomistic materials modeling and simulation used at more than 500 customer sites worldwide. Thousands of scientists and engineers in industry and research institutions use MedeA to understand complex processes such as mechanical failure, electrochemistry and ionic conductivity in batteries, and catalytic reactions; and to compute materials properties efficiently and systematically. MedeA helps to create better products while saving valuable research and development time and cost.

MedeA integrates world-leading structural databases (i.e., totaling over 1,100,000 entries), electronic structure programs, molecular dynamics and Monte Carlo methods with a host of powerful building, editing, and analysis tools in a unified environment thus allowing elaborate workflows to be used in a most efficient, easy to implement and reproducible manner. Its innovative high-throughput (HT) capabilities enable the full exploitation of increasingly available computing power.
