.. admonition:: **At-a-Glance**

    Embedded Atom Method (EAM) forcefield based simulations provide computationally efficient descriptions of structural, mechanical, and thermal properties of metallic systems.
    The |medea|\ :sup:`®`\ [#TM]_ *EAM* module provides straightforward access to EAM simulations in the |medea| |menvironment|.

    **Key Benefits**

    * **Productivity** - Fully utilizes the powerful LAMMPS simulation workflows within the |medea| |menvironment|

    * **Coverage** - Supports a wide range of properties for meteallic systems:

      - Structures
      - Energetics and structural properties of defects
      - Mechanical properties
      - Dynamical properties, such as melting points

    * **Flexibility** - Incorporates an extensive set of models:

      - Load models from |medea| |infomatica|
      - Use the |medea| |amorphousbuilder| to create models
      - Modify models with the powerful, yet intuitive simulation protocols
	of |medea| |mflowcharts|

:myquote:`Perform large scale simulations of metallic systems, spanning significant time scales using MedeA EAM`

Key Features
^^^^^^^^^^^^

* Support for Finnis-Sinclair format EAM forcefield files with simple extensions for template type assignment and referencing
* Support for atom type assignment template rules to facilitate construct-then-type model constructions for LAMMPS simulations
* Support for the Zhou et al 2004 [#Zhou2004]_ EAM parameterization supporting mixed alloys of:
  Cu, Ag, Au, Ni, Pd, Pt, Al, Pb, Fe, Mo, Ta, W, Mg, Co, Ti, and Zr

   The upper section shows the simulation of the melting point of
   a metallic system using a two region model, and described
   by an EAM forcefield with component functions in the
   inset graphs. The lower section shows screw
   dislocations and other defects on a metal surface.
