MedeA
   
Materials Exploration and Design Analysis

Scope

MedeA is a software environment which responds to the needs of materials scientists to have rapid access to materials data from experiment and to perform simulations in a single, user-friendly environment running on desktop or laptop computers.

The MedeA Environment provides direct access to a suite of modules including:

  • The world’s major crystallographic structural databases of inorganic materials
  • Advanced database search capabilities
  • Model building and editing at the atomistic level
  • State-of-the-art computational tools of structure and properties
  • An innovative database infrastructure to store and retrieve computed results
  • Visualization, display and analysis tools

MedeA is designed to address most materials issues such as structural, thermal, mechanical, chemical, electronic, optical, and magnetic properties of bulk materials, layered materials, surfaces and interfaces. MedeA’s simulation and informatics modules may be used individually, but the full power of the software lies in the use of these two methodologies in tandem. For example, their combination offers important advantages in large-scale screening.

Combining measured and calculated data offers new as yet untapped opportunities for predictive modeling of materials properties and chemical behavior.

 

Components of MedeA

MedeA modules MedeA integrates in a single environment the informatics/database module

  • InfoMaticA contains the following data files and offers advanced search and retrieval capabilities within a single interface
    • ICSD (Inorganics Crystal Structure Data)
    • NIST Crystal Data
    • User-created databases of computed results

  • Simulation
  • Productivity tools
    • Phonon: Prediction of vibrational and thermodynamic properties of materials
    • MT: Prediction of mechanical and thermal properties of materials

  • Analysis - Interactive display of results
    • total energies and binding energies
    • energy band structures
    • densities of states
    • atomic charges
    • magnetic moments

 

Features

  • MedeA runs on Windows® 9X, Windows® NT and Windows® 2000 operating systems
  • Flexible and intuitive searching capabilities of datafiles, eg. “search all compounds which contain Ti, are ternary, and do not contain a lanthanide”
  • Structures retrieved from the databases can be viewed, edited, and used as input for computations
  • The crystal structure editor allows adjustment of lattice parameters, add/replace/delete of atoms within a cell, the construction of supercells, and modification of the symmetry of a model
  • Construction of crystal structures from scratch with full utilization of space group symmetry
  • Powerful symmetry handling: offers user-controlled choice of symmetry constraints during model building/editing, automatic detection of space group of highest symmetry and automatic settings following crystallographic standards
  • Convenient export to standard Windows® applications such as Word® or PowerPoint® via clipboard
  • Connection and automatic export to ray tracing module (POV-Ray) for high quality graphics output
  • Export of structures in virtual reality markup language (VRML
  • Flexible, web based job dispatching and control combines full utilization of compute resources on a network with convenient job management under Windows®
  • State-of-the-art platform independent implementation using an open-source TCL/TK standard
